How does the mlx90614 IR temperature sensor work?
This example allows seamless data collection from a MLX90614 IR Temperature sensor and a computer when using LJLogM. If you have questions about I2C functionality with our LabJack devices please refer to the I2C AppNote, the low-level function page or the high-level driver pseudocode for I2C.
Can a mlx90614 be connected to a Raspberry Pi?
With MLX90614, you can distantly measure the objects’ temperature, even the temperature of the sky. This enables a wide range of tasks in science and technics. This article will show how to connect this device to the Raspberry PI microcomputer via the i2c bus.
How to send an array using Melexis mlx90614?
To do this, we need to first get the PEC value for the transmission which will be 2E0000, 2E = EEPROM address, 00 = LSB, 00 = MSB. The PEC value that gets returned by the calculator is 6F. Therefore we can now send the array (use the same configuration’s as the read transmission):
What’s the slave address of a Melexis IR temperature sensor?
There is a preprogrammed 7 bit slave address of 0x5A set by the factory. However the datasheet never mentioned that the default address for this sensor is 0.
What are the features of the Melexis mlx90614 thermometer?
Integrated into the MLX90614 are a low noise amplifier, 17-bit ADC and powerful DSP unit thus achieving high accuracy and resolution of the thermometer. The thermometer comes factory calibrated with a digital SMBus output giving full access to the measured temperature in the complete temperature range (s) with a resolution of 0.02°C.
How does a non-contact IR temperature sensor work?
The sensor uses IR rays to measure the temperature of the object without any physical contact and communicates to the microcontroller using the I2C protocol. Note: More Technical details about the MLX90614 sensor can be found in the MLX90614 datasheet linked at the bottom of this page.
What to do with the Melexis IR temperature sensor?
This AppNote will deal with what information to transmit to the Melexis IR temperature sensor instead of focusing on how to send it.
