Product Introduction
HW-036 is a digital temperature and humidity sensor, with the core component being the DTH11 sensor. The sensor contains a resistive humidity sensing element and an NTC temperature measuring element, and is connected to a high-performance 8-bit microcontroller. It can detect the temperature and humidity around the sensor and output this information in the form of digital signals from the S-pin.
Product parameters:
1. Power supply voltage: DC 3.3～5.5V
2. Output: Single bus digital signal
3. Measurement range: humidity 20-90% RH, temperature 0-50 ℃
4. Measurement accuracy: humidity ± 5% RH, temperature ± 2 ℃
5. Resolution: humidity 1% RH, temperature 1 ℃
