TSD14 / TSD15
Advantage:
·High temperature accuracy and low power consumption
·Large effective sensing area and high sensitivity
·Fast response time and high signal-to-noise ratio
Description:
It can achieve non-contact high-precision temperature measurement and real-time output of changing temperature values.
Function:
It contains a thermoelectric MEMS chip with sensitive voltage response to the target temperature and a high-precision NTC thermistor for environmental temperature compensation. Users can achieve temperature measurement function by combining digital signal conditioning chips or external MCUs. After being paired with a suitable external processing unit, the measurable target temperature range is -40℃ to +125℃, with a measurement accuracy of 2% over the entire temperature range; Within the temperature range of 35-42℃ for human body measurement, an accuracy of 0.2℃ can be achieved. The product can receive infrared thermal energy radiated by the target object within a certain distance, which is converted into corresponding voltage signals by sensors and output. Then, the VT relationship is calculated through external devices to obtain the target temperature value, and the changing temperature value can be output in real time.
