Very precise infrared non touch Temperature sensor less then 17.50 euro

I have made a very precise infra red thermometer. Available as a do-it yourself project.
it is as of now available on github [Wifi Thermometer][https://github.com/SpoturDeal/Esp32PreciseTemperature]
Most temperature sensors are based on an DS18B20 sensors, the disadvantage of this sensor is that is heats up itself. This results in a higher temperature and the temperature change is slower.
By using an InfraRed sensor you are able the measure the temperature in the field of view of the sensor. (you sensor could be 40C (104F) in the sun, but in field of view the temperature is on 21.2C (70F)
If you are using the sensor for controlling something else the precise temperature could benefit. The temperature are very fast because there is no cooling or heating of the sensor in our object measurement.
