None of them work - Accessory

None of the five work. I have used DHT22 with Arduino and esp8266 for years with no problems. I'm using the Adafruit DHT22 library.

Pros
  • Single channel digital signal output, two-way serial data port
Cons
  • Can't remember

Revainrating 1 out of 5

The readings of the temperature and humidity sensors do not correspond to the technical specifications.

They are cheap because they show constant low at 4% for humidity and constant high at 4% for temperature. Also, inaccurate readings were taken when connected to +3.3 VDC. Current when connected to +5 VDC. Current, all readings are consistently low at 8% for humidity and consistently high at 8% for temperature. Strange.

Pros
  • With mounting screw hole, easy to install and secure
Cons
  • Insecure

Pros
  • Humidifier parts and accessories
Cons
  • I have no particular complaints about it, everything is fine

The readings of the temperature and humidity sensors do not correspond to the technical specifications.

They are cheap because they are constantly low at 4% for humidity and constantly high at 4% for temperature. Also, inaccurate readings were taken when connected to +3.3 VDC. Current when connected to +5 VDC. Current, all readings are consistently low around 8% for humidity and consistently high around 8% for temperature. Strange.

Pros
  • Accessories
Cons
  • Protection
