AM2311 Single Bus Temperature And Humidity Sensor is a new high precision single bus temperature and humidity detector, which is based on AM2311 humidity capacitive digital temperature and humidity sensor chip. The AM2311 chip is a high quality, fast response, low cost, and anti-interference chip. This sensor is composed of a capacitive humid sensor to detect humidity in a wide range from zero up to 99.9% and a high precision temperature sensor in climate range from -40℃ up to +80℃, which is connected to an 8-bit microcontroller. The humid and temperature sensor is calibrated in the clean room  (laboratory), then calculates calibration coefficients and stored in the microcontroller program, to call it while sensing and during signal processing.
This temperature humidity sensor module is ultra-low power consumption, small size, and full auto calibration, which make it very suitable for portable applications. It can transmit the data to a long distance, thus is suitable for the industrial control from far away process. It is easily and completely interchangeable, so repairing process is simple and easy. It supports standard digital single bus output with long period stability. This module can be used in test and measurement tools and devices,  HVAC equipment, dehumidifier, inspection equipment, consumer goods, automatic control, data loggers, home appliances, humidity regulator, medical projects,   weather stations, and other humidity measurement and control and so on.
