Infrared thermometer
Use Atmel Mega328P chip as the main control, based on MLX90614, display with 3-digit 0.28-inch common anode digital tube
Powered by 18650 battery, boosted by IP5306 (Since MLX90614 is powered by 3V3 and 5V,
please select the corresponding LDO chip and buzzer)
Take the average after 3 measurements to reduce errors
One-key measurement, response time is about 300ms
Temperature compensation function: data is stored in EEPROM and saved when power off
Three-stage temperature zone alarm function: divided into green, blue and red zones, no alarm will be issued when the value is lower than the set value in the green zone, 5 beeps when the set value in the red zone is in the green zone, and 10 beeps when the set value is higher than the red zone
Buzzer switch: you can set whether to sound or not
