Advantages: Small size and low cost Easy to integrate Temperature measurement range: -70 to 380°C Accuracy up to 0.5°C in a wide temperature range (temperature measurement error: ±0.5°C (at room temperature)) Sensor temperature: -40 to 125°C (use ambient temperature) Measurement resolution is 0.02°C With M3 fixing screw holes, easy to install and fix. Size: 16.8mm(L)*11.46mm(W)*6.2mm(H), probe diameter 8.2mm Digital interface type: IIC (slave mode) or PWM Working voltage: 3.3V～5V
Introduction: The MLX90614 is an infrared thermometer sensor for non-contact temperature measurement. Both the IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same TO-39 can package. The MLX90614 integrates a low noise amplifier, a 17-bit ADC and a powerful DSP unit, so the thermometer has both high precision and high resolution. Measured temperature over the entire temperature range (0.02°C resolution) is available via the digital SMBus output.
The MLX90614 non-contact infrared sensor module can be output through a two-wire SMBus (system management bus) compatible protocol interface (IIC compatible) (0.02°C resolution) or a 10-bit PWM (pulse width modulation) output mode. The temperature range of the MLX90614 is calibrated at the factory, and the temperature measured by the sensor is the average temperature of all objects in the field of view. The PWM pins can also be configured in thermal relay mode.
Product Features: The MLX90614 is a low cost, non-contact thermometer. The output data is linearly proportional to the object temperature, with high accuracy and high resolution. The TO-39 metal package integrates the infrared induction thermopile detector chip MLX81101 (the temperature is measured by PTC or PTAT element) and the signal processing dedicated integrated chip MLX90302, which is specially used to process the infrared sensor output signal.
Application : High precision non-contact measurement Temperature comfort sensor for car air conditioning control system Air conditioner temperature sensing element for commercial and industrial buildings Windshield Anti-Fog Application Industrial moving element temperature control Printer temperature control Home appliance temperature control Multi-zone temperature control - two-wire communication can support up to 100 sensors Thermal relay/alarm Body temperature measurement
