Things needed in your TOOLBOX: What you need to install Personal Weather Stations successfully:

  • Screwdriver
  • pliers
  • Hammer
  • Saw

1. Correct positioning of your sensors

Choosing the correct location for your weather station is probably essential for any weather station installation. This is the most significant part to ensure the accuracy with which you will be able to measure all the different atmospheric conditions.

The two most important factors to consider for optimal installation are the height of the sensors and their distance from other objects.

A. The distance

Distance is the first crucial factor to consider when setting up your weather station. Two different distances are of particular importance during the installation process.

The first is the distance between the outdoor unit (containing the sensors) and surrounding objects. The second distance is between the outdoor unit and the base station.

B. rain shadow

Trees and walls can cover or cast a “rain shadow” on the unit, giving you a completely wrong reading from the rain gauge 1). The effect of a tree should be obvious, but the “rain shadow” deserves some further explanation.

Say, for example, the wind is blowing in the direction of the house while it is raining, and the rain gauge is placed too close to the wall on the opposite side of the house. The wall creates a “rain shadow,” i.e., the wind blows the rain over the rain gauge, receiving only a portion of the actual rain.

The same goes for wind speed and direction. Large objects influence wind speed and cause the wind to swirl, making it very difficult to get an accurate reading of wind direction.

At this point, you may be frustrated and wondering where you can put your deep L sensors, so they don’t get influenced by something. You’ll be happy to know that there is a rule of thumb to follow.

You might not be so happy to know that the rule of thumb follows a 4 X 1 rule. This means that deep L sensors should be placed at a distance four times the height of the nearest structure. If the structure is 3 m high, the deep L sensors should be placed 12 m from it.

C. Distance between the base and outdoor unit

Wireless connections are becoming the norm for most mid to high-end home weather stations. The ability to place the sensors anywhere outside the home and communicate seamlessly with the base station without additional cables or installations makes them very attractive to most home users.

D. Height

The second crucial factor when choosing a site to determine the accuracy of your sensor readings is the actual physical height of your unit above the ground.

The first reason is to get an accurate humidity reading. The accuracy of the hygrometer can be seriously influenced, especially when placed in a garden or an area containing plants, grass, or even bodies of water. 

Temperature is another variable that the surface can also influence under the sensors. Whether the sensor unit is installed on the ground or a roof, the surface of each sensor absorbs and reflects/radiates much of the sun’s heat into the surrounding atmosphere 2).

Therefore, when the sensors are placed too close to the surface, the thermometer will not be able to give an accurate reading. (Reflected/radiated heat from the ground below is added to the atmospheric temperature sensed by the thermometer).

Fortunately, you don’t have to be completely discouraged because the solution to this problem is not so complex. Just make sure the sensor array is about six feet above the ground surface. This height is sufficient to make the influence of surrounding objects and surfaces negligible.

Most quality weather systems come standard with brackets to mount the sensor unit (usually around a standard pole). You will be able to get a suitable mast from most of these manufacturers. You can even save money by purchasing a galvanized post that is long enough (to prevent rusting) from your local hardware store.

Be sure to take note of the width or type of post/surface your Deep L Sensor Array brackets will use before purchasing any accessories. Your weather station documentation should be able to provide you with this information.

2. Roof sensors

Most of us don’t have a big enough garden to place the sensor far away from any obstructions. Placing the sensor unit on your roof or mounting it sideways on a pole about 2.5 meters from the bottom of the roof will give you the best possible readings for all weather conditions.

Attention! This is a potentially dangerous exercise, so have a professional installer do it for you if you are not entirely confident and can do it yourself safely. 

Remember that you should replace the batteries approximately every two years. So make sure that the detection unit is always accessible to replace them and carry out occasional maintenance.

Tips To Get the Best Video in Low Light

Photography is directly linked to light. This plays a decisive role in the composition and aesthetics of the image, as in its final quality. Indeed, when you take photos in low light because it is lacking, it may seem difficult to get beautiful photos.

We are going to see how to best control your device to understand shooting in low light. We will cover the basic exposure and focus settings, I will also give you some tips so that you will never be disappointed when you return from an exhibition, a concert, or a birthday.

What is Low Light?

Observe your surroundings. Depending on the time, place, season, weather, natural light ( from the sun ) is never the same. When the sun is shining and the sky is clear, the amount of light is important. It is a “high light” situation. When the sun is veiled, in the morning, in the evening, the amount of light is lower. This is a “low light” situation.

The main advantage of low lights is that you can take different photos and videos, with more relief, shadow play, and nice blacks and grays. They should not be left out!

Tips To Get the Best Video in Low Light

Here, I’m going to walk you through some tips and tricks for getting great low-light photos. Before proceeding with the techniques, make sure you learn all the manual modes of your video camera for low light conditions, as it allows you to control every functional aspect of your camera.

1. Choice of Light Measurement Mode

Pay attention to the light measurement mode you use ( find out more ). During a show, for example, the subject is often very brightly lit and the rest of the scene very dark. Matrix metering tends to expose the entire image. If the subject is small and bright against a dark background, it will be overexposed. If it is small and dark on a light background it will be underexposed.

To remedy the problem, it is necessary either to correct the exposure of several environments or to engage the spot metering ( more delicate to use ) by measuring the light on the main subject.

2. The Stability Of The Case

When you shoot, the slightest movement can introduce motion blur. This is why you should use the shortest possible exposure time. If you cannot use a sufficiently short exposure time, you must remember to stabilize your case as much as possible. Do you have the option of using a tripod or a monopod? Do not deprive yourself of it! You can then use a longer exposure time. But not all circumstances allow you to use a tripod.

The grip of your case is very important: you must tighten it firmly. You can also rest your elbows against your chest to stabilize yourself more. Do not hesitate to lean against a wall or a railing. This will help you move less. When the trigger is to release, gently squeeze the shutter release button so that you do not move too much.

3. Use Light Sources Advantageously

Low light means that the lighting is dim, but not nonexistent. So, do not hesitate to integrate the available light sources as much as possible. In the image below, I chose to light the lamp located above the potter in order to illuminate the scene, even if the idea is to highlight the craftsman. Without this lamp, the amount of light was not sufficient to achieve a short exposure time and have a clear photo. Thanks to this additional light source, I was able to use a shorter exposure time.

In some cases, if the lighting conditions are really very poor, you will use the flash built into your camera. You can then have a short exposure time and get a clear photo. However, the colors will be distorted because of this artificial lighting. So try to avoid this fallback as much as possible.

4. Auto ISO setting

Auto ISO can be seen as a ‘ beginner ‘ mode until the day after shooting indoors in manual ISO, you forget to change the ISOs at the end of the session and you find yourself having to photos in bright sunlight at ISO 6.400.

Conclusion

Taking good photos and video in low light is possible!

By using settings that are right for your camera and your subject, you can take good-quality photos in low light. Recent cameras deliver images whose noise level is very low up to ISO 3,200 and quite manageable in post-processing up to ISO 12,800. Another good reason to dare to photograph in low light!
