A simple strategy to automatically control the speed of fan using DHT22 sensor. According to the temperature sensed by temperature and humidity sensor the resistance of the fan will be adjusted to change the fan speed. It's fairly straightforward to use, however needs careful arrangement to grab...
比如:“Temperature: -40.0099983215C / -40.0180015563F. Humidity: -4.44%”,这个数值典型就是没连上,为避免信号冲突,微处理器应驱动DATA 在低电平,所以sht10的data和vcc之间要串一个10kΩ的上拉电阻(其实就是一个简单的10kΩ的电阻),注意是串联,两端分别连接data和vcc之间即可。
This is a library for the BME280 humidity, temperature & pressure sensor Designed specifically to work with the Adafruit BME280 Breakout ---> http://www.adafruit.com/products/2650 These sensors use I2C or SPI to communicate, 2 or 4 pins are required to interface. The device's I2C address...
HTS221 Capacitive digital sensor for relative humidity and temperature
This temperature & humidity sensor provides a pre-calibrated digital output. A unique capacitive sensor element measures relative humidity and the temperature is measured by a negative temperature coefficient (NTC) thermistor. It has excellent reliability and long term stability. ...
