What is a ambient air temperature sensor for?
The Ambient Air Temperature Sensor measures the temperature outside the passenger compartment and is usually mounted inside or near the front bumper. The sensor provides input to automatic HVAC systems to help control the interior temperature of the automobile.
What are the symptoms of a bad AC control module?
Symptoms of a Bad or Failing AC Control Module
- Inconsistent cooling. Because the AC control module controls and regulates all of the functions of the system, you may begin to notice cooling inconsistencies when there is a problem.
- Out-of-date software updates.
- Uneven air distribution.
How many Sun sensors are there?
In order to detect the Sun’s attitude in two directions, at least three coarse sun sensors are usually needed, unless a pyramid coarse sun sensor is used.
What is sunshine sensor?
The BF5 Sunshine Sensor is a versatile, multi-purpose solar radiation sensor. It uses an array of photodiodes with a unique computer-generated shading pattern to measure incident solar radiation. A microprocessor calculates the global and diffuse components of the radiation and determines the sunshine state.
What is a sun sensor used for?
A sun sensor is a navigational instrument used by spacecraft to detect the position of the sun. Sun sensors are used for attitude control, solar array pointing, gyro updating, and fail-safe recovery.
What does a pyranometer measure?
Simply said a pyranometer is a device that measures solar irradiance from a hemispherical field of view incident on a flat surface. The SI units of irradiance are watts per square metre (W/m²).
How do star sensors work?
Star sensor is one of the precise attitude determination sensors. It is an electro-optical system that takes an image from a set of stars and by comparing it with the star catalogue determines angle deviation of the satellite and modifies its attitude.
