Power Pins:

  1. Vin - this is the power pin. The chip can use 2.5-5VDC for power. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro, use 5V. For a 3.3V controller , connect to 3.3V GND - common ground for power and logic
  2. SCL - I2C clock pin, connect to your microcontrollers I2C clock line. This pin has a 10K pullup resistor to Vin
  3. SDA - I2C data pin, connect to your microcontrollers I2C data line. This pin has a 10K pullup resistor to Vin
  4. ADR - This is the I2C address selection pin. This pin has a 10K pull down resistor to make the default I2C address 0x44. You can tie this pin to Vin to make the address 0x45
  5. RST - Hardware reset pint. Has a 10K pullup on it to make the chip active by default. Connect to ground to do a hardware reset!
  6. ALR - Alert/Interrupt output. You can set up the sensor to alert you when an event has occured. Check the datasheet for how you can set up the alerts

Package Included:

I bought an Arduino a few years ago, and I am just now using it. I tried to create a temperature sensor with the DHT11, but it was very slow and the humidity was not accurate. I then ordered some BME280 sensors, but those sensors were horribly inaccurate— worse than the DHT11s. I found these and ordered them and they have worked flawlessly for a few weeks now. Amazing product.

Can’t argue with the price and accuracy of these little sensors. Option onboard to get a second address on the one-wire which offers the convenience for an indoor/outdoor or supply/return dual use circuit when using two on the same one-wire.

All bad units!
