NodeMCU Code Example:

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.%03d\r\n»,
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
