I tried to retrieve humidity and temperature using the DHT11 sensor with ESP8266. However, I have been getting a compiling error such as "lua:4: unexpected symbol near ',' ". If possible, could anyone also point out the other potential errors in this code? My code looks as follows: 
Code: Select all
pin = 1
status, temp, humi, temp_dec, humi_dec = dht.read(pin)--read dht11 from pin
if status == dht.OK then --check status is ok and print temperature and humidity
print(string.format( "DHT Temperature:%d.%03d;Humidity:%d.%03d" )
math.floor(temp),
temp_dec,
math.floor(humi),
humi_dec
)
elseif status == dht.ERROR_CHECKSUM then --else print either status
print( "DHT Checksum error." )
elseif status == dht.ERROR_TIMEOUT then
print( "DHT timed out." )
end
