I plugged grove DHT22 to the socket D7 & D8 of grovepi, then I made python code based on example like
[temp1, hum1] = grovepi.dht(7,1);
print (“1 temp=”, temp1, “thum=”, hum1)
[temp2, hum2] = grovepi.dht(8,1);
print (“2 temp=”, temp2, “thum=”, hum2)
After got sensor values, it obtained was the opposite.
For example, when I test humidity of D8 sensor, the high humidity was printed in hum1.
I don’t know what’s happen.
I would appreciate it if you could help, thanks.
