With the rapid development of the Internet of Things and industrial automation, temperature sensors, as core sensing components, have a direct impact on system performance due to their accuracy and efficiency. Traditional contact temperature measurement methods pose challenges such as cross-infection risks, interference with the measured object, and delayed response. Non-contact solutions face complex integration and insufficient accuracy. The MTP10-A6F55D digital temperature sensor from MFrontier, with infrared thermopile technology, redefines the standard for non-contact temperature measurement.
1. Infrared Thermopile Temperature Measurement Solution
The infrared thermopile temperature measurement solution uses the thermopile effect (Seebeck effect) to measure temperature. The principle is based on the energy conversion between infrared radiation emitted by an object and thermoelectric materials. When an object above absolute zero radiates infrared radiation, the thermopile sensor receives this radiation through an array of thermocouples. Different wavelengths of infrared radiation correspond to different temperatures. The sensor uses a filter to select specific wavelengths and converts the received infrared radiation into a voltage signal.
Thermopile temperature detection technology measures temperature without physical contact, but requires an integrated cold-junction solution to improve real-time compensation. It is suitable for medical and industrial applications, offering high accuracy and strong interference immunity.
2. MFrontier MTP10-A6F55D Digital Temperature Sensor
The MSI Advanced MTP10-A6F55D is a single-channel digital infrared thermopile temperature sensor housed in a compact TO39 package. It integrates a thermopile temperature sensor, PGA, A/D converter, DSP, MUX, and communication protocol, making it easy to integrate into non-contact temperature measurement applications.
Compared to other temperature sensors, the MTP10-A6F55 offers the following advantages:
Fully digital output simplifies system integration.
Built-in IIC communication protocol directly outputs digital temperature signals, eliminating the need for external A/D converters. This reduces system component count, development costs, and PCB space.
Calibrated over a wide temperature range.
The MTP10-A6F55D is factory calibrated over a wide temperature range and can operate in an ambient temperature range of -20°C to 85°C. It can measure temperatures between -20°C and 300°C.
Ultra-small package and low power consumption.
The TO39 metal package makes it compact and suitable for embedded devices. Operating current is as low as 600μA (continuous mode) and sleep current is only 5.0μA, extending the battery life of battery-powered devices.
High Interference Resistance and Optical Optimization
Our proprietary longwavepass filter achieves ≥80% transmittance in the 5.5-14μm band and a 1% cutoff below 5μm, effectively shielding against short-wavelength infrared interference and improving measurement stability in complex environments.
