3 Pack KY-015 Smart 3pin DHT-11 DHT11 Digital Temperature and Relative Humidity Sensor Module + PCB DIY Starter Kit

Exactly as expected i.e. legit KY-016 units. I have purchased these from several sources. This is the first time that I have seen them with Prime shipping on Amazon. If you are buying a lot of these, you can get them elsewhere cheaper. But if you only need 3, this is an easy way to get them quickly.

That sensor is unreliable with giving false positive or no signal at all. One of the sensor had poor soldering done on the pins.Pros :- NoneCons :- Poor design for sensor placement- Unreliable- Expensive for what it is

These are poor quality and none of the three sensors worked. The power led lit but they do not register touch

Sensors were not super accurate for testing

This is NOT analog in anyway. The Hall Sensor used is a 44E-402.

Very sloppy build. I haven’t been able to get one of them to work yet.

I have two other similar IR receivers, one made by Elegoo and the other by Quimat. They are both very reliable. These IR receivers have more error in their signal making them unreliable. I have to re-press the button on the IR transmitter (remote) very often. I am very disappointed. I need more IR receivers, but I'll have to order another brand.
