Description:DHT Shield is a digital temperature and humidity sensor shield based DHT11.

Features:

• Temperature: 0~60°C (±2°C)
• Humidity: 20-90%RH (±5%RH)

Pins:

Arduino Code

• Install DHT sensor library
• Test Code

NodeMCU Code

pin = 4
status, temp, humi, temp_dec, humi_dec = dht.read(pin)
if status == dht.OK then
— Integer firmware using this example
print(string.format(“DHT Temperature:%d.%03d;Humidity:%d.%03drn”,
math.floor(temp),
temp_dec,
math.floor(humi),
humi_dec
))– Float firmware using this example
print(“DHT Temperature:”..temp..”;”..”Humidity:”..humi)elseif status == dht.ERROR_CHECKSUM then
print( “DHT Checksum error.” )
elseif status == dht.ERROR_TIMEOUT then
print( “DHT timed out.” )
end
