The recommended PCB layout for optimal performance of the SAR90505 includes keeping the sensor away from high-frequency components, using a solid ground plane, and minimizing the distance between the sensor and the microcontroller. Additionally, it is recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
Calibration of the SAR90505 involves adjusting the sensor's offset and gain to compensate for variations in the environment and the target material. This can be done by taking multiple readings at different distances and using a calibration algorithm to determine the optimal offset and gain values.
The maximum operating temperature range for the SAR90505 is -40°C to 125°C, although the optimal operating temperature range is -20°C to 85°C. Operating the sensor outside of this range may affect its accuracy and reliability.
Yes, the SAR90505 can be used in outdoor applications, but it may require additional protection from environmental factors such as moisture, dust, and extreme temperatures. It is recommended to use a weather-resistant enclosure and to follow proper installation and maintenance procedures.
The SAR90505 uses a proprietary algorithm to reject interference from other sensors or devices. Additionally, it has a built-in filter to reduce electromagnetic interference (EMI). However, it is still recommended to follow proper installation and shielding practices to minimize the risk of interference.
