Reading DHT22 and Light sensor data using NodeMCU dev board

Experimented with reading DHT22 amd Light sensor modules using NodeMCU ESP12E development board. Main problem I had that timer did not work on old firmware, had to update it ( read previous post ). Other that that all went fine and could read data.One strange thing is that I am getting temperature a little bit higher than actual. Not sure why is that, maybe because board is powered by 3.3v and not 5v. Will have to find out that later.Code:if not tmr.alarm(0, 5000, tmr.ALARM_AUTO , function() print("Starting to read data:") light = or "" print("Light:"..light) pin = 4 status, temp, humi, temp_dec, humi_dec = dht.readxx(pin) if status == dht.OK then -- 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 end) then print("whoopsie") end
