Technical summary
Description
The MLX90614 ESF is an infrared thermometer for non-contact temperature measurements. The infrared-sensitive thermopile detector chip and the signal-conditioning ASIC are integrated in the same TO-39 package. The MLX90614 GY-906 integrates a low-noise amplifier, a 17-bit ADC and a powerful DSP unit, which gives the thermometer high accuracy and resolution.
The user can configure the digital output as PWM. By default, the 10-bit PWM is configured to transmit the measured temperature continuously in the -20 to 120°C range, with an output resolution of 0.14°C.
Features:
- Operating from a 3.3V to 5V input, the module has a built-in power regulator IC.
- Standard I2C interface with 2 built-in pull-up resistors
- When measuring temperature, please keep a measuring distance of 1cm
- Small size, low cost
- Easy to integrate
- Factory calibrated over a wide temperature range: -40 to 125°C for the sensor temperature and -70 to 380°C for the object temperature.
- High accuracy of 0.5°C over a wide temperature range (0..+50 C for Ta and To)
- Medical accuracy of 0.1°C in a limited temperature range available on request
- Measurement resolution of 0.01°C
- SMBus-compatible digital interface for fast temperature readings and building sensor networks
- Customizable PWM output for continuous reading
- Simple adaptation for 8 to 16V applications
