The DHT11 Temperature and Humidity Sensor features a temperature & humidity sensor complex with a calibrated digital signal output. By using the exclusive digital-signal acquisition technique and temperature & humidity sensing technology, it ensures high reliability and excellent long-term stability. This sensor includes a resistive-type humidity measurement component and an NTC temperature measurement component, and connects to a high-performance 8-bit microcontroller, offering excellent quality, fast response, anti-interference ability, and cost-effectiveness. This DHT11 Temperature and Humidity Sensor uses a power supply of 3V to 5.5V DC. When power is supplied to the sensor, it does not send any instruction to the sensor for one second in order to pass the unstable status. One capacitor valued at 100nF can be added between VDD and GND for power filtering. Specification:- Operating Voltage: 3.5V to 5V Operating current: 0.5mA-2mA (measuring) 100uA (standby) Output: Serial data Temperature Range: 0°C to 50°C Humidity Range: 20% to 90% Resolution: Temperature and Humidity both are 16-bit Accuracy: ±1°C and ±1%Rh
