EC-buying GY-906 MLX90614ESF Non-Contact Infrared Temperature Sensor Module IIC I2C Serial for Arduino
The size and wavelength distribution of infrared radiation energy of an object are closely related to its surface temperature. Therefore, by the object itself
The measurement of infrared radiation can accurately determine its surface temperature, and infrared thermometry uses this principle to measure temperature. Infrared the thermometer is composed of optical system, photodetector, signal amplifier, signal processing and output. Optical system convergence the infrared radiation energy of the target in its field of view, and the size of the field of view is determined by the optical parts and their positions of the thermometer. Infrared Energy Concentration Focus on the photodetector and convert it into a corresponding electrical signal. The signal goes through amplifiers and signal processing circuits, and according to the instrument The internal algorithm and target emissivity correction are converted into the temperature value of the measured target
MLX90614 PINS
Application For
Note
All the communication and refresh rate timings are given for the nominal calibrated HFO frequency and will vary with this frequency’s variations.
1.With large capacitive load lower PWM frequency is recommended. Thermal relay output (when configured) has the PWM DC specification and can be programmed as push-pull, or NMOS open drain. PWM is free-running, power-up factory default is SMBus, refer to section 8.6, “Switching between PWM and SMBus communication” for more details.
2.For SMBus compatible interface on 12V application refer to Application information section. SMBus compatible interface is described in details in the SMBus detailed description section. Maximum number of MLX90614 devices on one bus is 127, higher pull-up currents are recommended for higher number of devices, faster bus data transfer rates, and increased reactive loading of the bus. MLX90614 is always a slave device on the bus. MLX90614 can work in both low-power and high-power SMBus communication. All voltages are referred to the Vss (ground) unless otherwise noted. Sleep mode is not available on the 5V version (MLX90614Axx)

this is the 2nd one I purchase, it seems to break extremely quickly and very noise prone .. there are some libraries available for programing on Arduino But if using it on a machine not recommended .
