Melexis Contact-less Infrared Sensor - MLX90614 5V
MLX90614 non-contact IR temperature sensor measuring -70 °C to +380 °C over a 90° FOV via I2C. This is the 5 V variant suited for classic Arduinos; the 3 V version is for modern 3.3 V microcontrollers.
Pinout
- VCC
Power input for the MLX90614 sensor; Adafruit states there is a 5V version and that the four pins are power, ground, I2C clock, and I2C data.
