This is a RS485 communication based temperature and humidity sensor. It is based on the SHT20 sensor that has a microcontroller that will convert the sensor signal to RS485 protocol.
You simply connect the red wire to 9v-36v, the black wire to ground and yellow for RS485 channel A and white for RS485 channel B. The sensor is encase in a black abs enclosure allowing you to protect the circuit board from the elements, you can also remove the enclosure to clean the casing when you want. It also has an M3 mounting hole for affixing to any frame that you desire.
