AM2305B Product Overview:

AM2305B digital temperature and humidity sensor is a calibrated digital signal output of the temperature and humidity combined sensor. It uses a dedicated digital modules capture technology and the temperature and humidity sensor technology to ensure that products with high reliability and excellent long-term stability. Sensor includes a capacitive humidity sensing element and a 18B20 temperature measurement devices, and with a high-performance 8-bit microcontroller connected. Therefore, the product has excellent quality, fast response, anti-interference ability, high cost and other advantages. Each AM2305 sensors are calibrated in a precision humidity calibration chamber. Calibration coefficients stored in the form of a program OTP memory, internal sensor detection signal in the process to call these calibration coefficients. Single-wire serial interface, the system integration becomes simpler and quicker. Ultra-small size, low power consumption, signal
transmission distance up to 20 meters, making all kinds of applications and even the most demanding applications the best choice is. Products for the 4-pin single row pin package. Easy connection, special packages according to user needs and available.
