Review on π‘οΈ HiLetgo 2pcs Si7021 Temperature Humidity Sensor for Arduino GY-213V-SI7021 - Industrial High Precision with I2C Interface by Leo Torres
Fast and accurate Good for testing, measuring and checking
I have connected 4 of these to Raspberry Pi Zero W single board computers around the house. They respond quickly to temperature and humidity changes and are more accurate than the BME280. Two of them are outdoors and two are indoors. They serve for months without any problems. The price is great: about $5 each. The SI7021 chip itself costs about $3, so $5 for a breakout board is a good deal and better than any of the competition I've seen. I just bought 2 more for a few more temp/humidity stations.
- Great for outdoor activities
- Not sure
