Gravity: I2C Non-contact IR Temperature Sensor
(MLX90614-DCI)
SKU:SEN0263
INTRODUCTION
We can divide temperature measurement in to two types: contact and non-contact. Contact
measurement can only accurately measure temperature when the testing object and the sensor
reach thermal equilibrium. This can mean longer response times and reading inaccuracies offset
by ambient temperature. By contrast, non-contact measurement uses infra-red radiation to
measure the temperature and does not require a direct touch. Additionally, this method of
measurement can be read quickly and accurately.
In recent years non-contact measurement methods have been used for medical, environmental
monitoring, home automation, automotive electronic, aerospace and military applications.
Our latest infrared temperature measurement module is the MLX90614. This module measures
the surface temperature by detecting infrared radiation energy and wavelength distribution. The
IR temperature probe consists of an optical system, photoelectric detector, amplifier, signal
processing and output module. The optical system collects the infrared radiation in its field of
view and the infrared radiation energy is converted in to corresponding electrical signals when
converging on the photoelectric detector. After being processed by the amplifier and signal
processing circuit, the signal is converted in to a temperature value. The MLX90614 is self
calibrating and has a low noise amplifier integrated in to the signal processing chip. The chip
itself is a 17-bit ADC and DSP device, giving accurate and reliable results.
SEN0263 (MLX90614‐DCI), due to its small field of view (FOV = 5°), is more suitable for industrial
applications where the detection distance can be longer. In general applications, you can
use SEN0206(MLX90614‐BCC)
