Top 5 Positive Customer Reviews for خليط الاستشعار
Well this sensor is unuseable, not problem of the seller, but this sensor reacts on almost every gas, not just CO2, which sucks for me, because you dont know where is problme right now...
Everything was perfect. Ordered 5 pcs and all work well with the latest MicroPython firmware on ESP8266 board. Packaged also very well in a plastic case where all sensors were safe.
