Thanks gerry for your suggestion but in my case it doesn't work. I changed from Physical pins (rev.2) to
BCM gpio
following my wiring connection
but I always received wrong values:
{"_msgid":"e68c589b.d4d8f8","topic":"rpi-dht22_test","payload":"0.00","humidity":"0.00","isValid":false,"errors":4,"location":"Test_T&H","sensorid":"dht22"}
I tried also to change the connection pin to other pins but nothing happened.
I thought the possible problem could be the correlation between the pins in the list node-red-contrib-dht-sensor and the real pins so I changed (and tested) all the proposed pin numbers into the node-red-contrib-dht-sensor list, but nothing.
Following my wiring pin table:
Could the problem be a no compatibility of the sensor DHT22 AM2302 with the node-red-contrib-dht-sensor? Or does it depend from my hardware configuration?
Does anyone know if there is an alternative palette to node-red-contrib-dht-sensor to control a DHT22 sensor into nodered?
