Arduino project | how to make a contactless thermometer

04/10/2016· This Arduino project: a contactless thermometer is good for anyone who wants to measure temperature from any object without touching it. The infrared sensor detects infrared radiation that emitting from an object and convert the value to digital data and sent the data to Arduino board via I2C interface. The sensor I use in this project is mlx90614,infrared and ambient temperature sensor…

Design of a contactless body temperature measurement ...

The two temperature sensors LM35 (S1) a contact type and MLX-90614 (S2) contactless are used in this proposed monitoring system as shown in Figure 5. The LM35 sensor is a precise sensor which directly converts the output voltage into temperature in Celsius. This conversion is programmed into Arduino panel using the (1). This sensor is better than thermistor due to linear output and low ...

MLX90614 reads low temperatures - Sensors - Arduino Forum

29/07/2021· Hello everyone, I am building an infrared contactless thermometer using this sensor, the MLX90614, but I always face the same problem. Firstly, I bought the BAA version of that sensor, but it always measured lower temperatures than it should. I thought it was because of the wide FOV, so I secondly bought the DCC version, which supposedly was more accurate. However, I still had the …
