AM2301 Temperature & Humidity Sensor The AM2301 temperature and humidity sensor is a digital sensor that measures both temperature and humidity. It uses a capacitive humidity sensor and a thermistor to measure the humidity and temperature, respectively. The sensor communicates with a microcontroller or other host device using a digital protocol such as the Single Wire Protocol (SWP) or the Inter-Integrated Circuit (I2C) protocol. The sensor can operate over a wide range of temperatures and humidities, and it has high accuracy and a fast response time. It is commonly used in applications such as weather stations, HVAC systems, and industrial process control. The sensor includes a capacitive humidity sensing element and an NTC temperature measuring element, connected with a high-performance 8-bit single-chip microcomputer, so it has the advantages of ultra-fast response and strong anti-interference ability. Low cost, 3 to 5v power and i/o, 2.5ma max current use during conversion. 1-1.5ma measuring current, 40-50 ua standby current. It has only 3 wires, including power and ground, meaning only one digital pin is required to interface it to a microcontroller. Applications: HVAC Dehumidifier Weather station Humidity regulator Medical treatment Home appliances
