🌡️ Advanced AM2302 Digital Temperature and Humidity Measurement Device Review

Finally got around to using these sensors because. I already had one on the Wemos Mini D1 shield. The sensor works without problems. I set up a second Wemos Mini D1 board with these sensors and they don't work. Looked at the DHT22 sensor and it's low and lo and behold, no data. Very disappointing.

sensor works well for my needs. i really like it Temperature reports appear to be accurate except when placed in direct sunlight when it seems to jump more than it should. The humidity also seems to be pretty good (99% when it rains). The reason I didn't give it five stars is because it takes a few seconds when the temperature changes significantly (like taking it outside where it's 20 degrees cooler). Minutes for the reported temperature to slowly approach the correct value.

they work great with raspberry pi. You can see in the graph that I have 3 DHT22 sensors and they all agree within about half a degree Fahrenheit. The two I put together in that order (blue and yellow lines on the chart) are even closer, typically within 0.2 degrees Fahrenheit. each other. The green line is a sensor that I accidentally connected with too small a resistor (2.2 kΩ instead of 10 kΩ). Smoke started pouring out and it was too hot to touch. When I realized what I had done I wanted to…
