AM2305B High Precision Single Bus Communication Pipeline Temperature Humidity Sensor Probe For Industrial Use
Product Overview:
The AM2305B is a temperature and humidity sensor with calibrated digital signal output. It is equipped with a newly - designed ASIC chip, an improved MEMS semiconductor capacitive humidity sensor, and a standard temperature sensor, and its performance has reached the industry's advanced level.
Application Range:
The AM2305B is widely used in consumer electronics, medical, automotive, industrial, meteorological and other fields, such as HVAC, dehumidifiers, refrigerators and other home appliances, as well as testing and detection equipment and other related temperature and humidity detection and control products.
Principle and Structure:
The AM2305B contains a capacitive humidity - sensing element and a high - precision temperature - measuring element, which are connected to a high - performance 8 - bit single - chip microcomputer. It uses a dedicated digital module acquisition technology and temperature and humidity sensing technology. Each sensor is calibrated in a highly accurate humidity calibration chamber, and the calibration coefficients are stored in the single - chip microcomputer in the form of a program. The internal sensor calls these calibration coefficients during the processing of the detected signal.
