that it can detect even the slightest changes in the environment, making it ideal for applications such as HVAC systems, dehumidifiers, and weather stations. **Ease of Integration and Use** The sensor's single-wire serial interface makes it incredibly easy to integrate into any Arduino or elect...
Get temperature and humidity sensor with free return and fast delivery. The temperature and humidity of the respiratory system is measured by the front, back, etc.
The Arduino microcontroller, being the processing unit of the system, gets the sensor's measured value and compares it with the set threshold. The results are: when the measured room temperature is less than the minimum of the threshold value; then, the microcontroller turns on the heater. If...
Each DHT11 sensor is calibrated in an extremely accurate humidity calibration chamber. The calibration coefficients are stored in the OTP memory as a program, and these calibration coefficients are called internally during the processing of the detection signal. The single-wire serial interface makes ...
