Single Bus DHT11 Digital Temperature and Humidity Sensor for Arduino DHT11 Probe
This DHT11 Temperature Humidity Sensor module integrates required components on a small PCB.
The sensor includes a resistive-type humidity measurement component, an NTC temperature measurement component, and a high-performance 8-bit microcontroller inside, and provides calibrated digital signal output.
It has high reliability and excellent long-term stability, thanks to the exclusive digital signal acquisition technique and temperature & humidity sensing technology.
Each DHT11 is strictly calibrated in the laboratory that is extremely accurate on humidity calibration.
The calibration coefficients are stored as a program in the OTP memory, which is used by the sensor’s internal signal detecting process.
The single-wire serial interface makes system integration quick and easy. Its small size, low power consumption, and up-to-20 meter signal transmission making it the best choice for various applications, including those most demanding ones.
