The Tpis 1S 1385 Calipile Sensor SMD is among the most intelligent and smallest infrared devices ever made with multi-functional capabilities. The single compact sensor has calipile’s integrated electronics, which provide digital conversions and other processes and filter the data to enable its multi-function capabilities. Being a surface mount technology (SMD), the sensor device is ideally mounted directly to the surface of a circuit board.

The TPiS 1S 1385 Calipile Sensor SMD is equipped with a couple of functions that make it crucial for different life aspects. Additionally, its ability to adapt to other functions contributes significantly to its diverse use in military, industrial and residential applications. Below are some of the essential functions adopted by the device:

Motion Detection

Motion detection is a function employed by many devices, thanks to the Calipile Sensor. Intelligent doors can use the motion detection function and even surveillance cameras mounted for security purposes. The smart doors use the sensor as a safety feature that prevents individuals from getting squeezed by the door’s mechanism. As a result, when an object stands in the way of the door, it breaks the circuit to the sensor causing the door to re-open to avoid impact with the obstructing object. The surveillance cameras also use motion detection technologies in alerting their operators on things in motion within the camera’s location for appropriate action to be taken. 

Presence Monitoring

The presence monitoring function is used mainly by military personnel and installed in high-security level access areas. The Calipile sensors may be installed to trigger an alarm whenever a body in motion is present in the monitored area. These presence monitoring features may enable the cameras to acquire a target on the device via the emitted infrared energy as it monitors the presence of the body.

Temperature Measurement

All bodies emit infrared radiations as long as their temperatures are beyond the absolute temperature. It means that the sensor may be able to measure the temperature of a surface depending on the amount of Infrared radiation emitted by the body. The difference in the intensity of the infrared waves received by the TPiS 1885 Calipile Sensor SMD is what shall cause the ability to measure the different temperatures.

Outstanding Features

  • Over-Temperature Interrupt 

The temperature interrupt features are primarily used in areas where flames are likely to burst out. When exceeded, a temperature is set by the experts. An alarm shall get triggered for appropriate actions to get taken in correcting the situation. In other areas, the temperature interrupt function of the Calipile sensors may be integrated by the experts with other systems such as the fire extinguishers, which shall correct the temperature levels via the installed mechanisms. The over-temperature interrupt function is made possible by the ability of the sensors to measure the temperatures of objects from a distance. When the temperature of a surface exceeds the required standard temperature or even occurs to burn in a larger area than the speculated one, triggers shall go off due to the increased Infrared radiation being received by the Calipile sensors. This increase in infrared radiation is due to the rise in the body’s temperature, subsequently leading to more Infrared waves onto the sensor.

Highly Effective and Sensitive.

Despite the TPiS 1s 1385 Calipile Sensor SMD device having very high effectiveness on measuring, its efficacy is limited to a sensing distance of up to 3 meters without requiring the use of supplemental lensing. The sensitivity of these Calipile SMDs is very high. They tend to register even the most minor deviations in signals from the surfaces being measured. Additionally, the device has a wide field of view of 120°, which is slightly wider than its predecessors. The device is integrated with a 50 microwatts low power processing of signals ability.


Despite being housed in ultra-compact housing, the device has a thermopile sensor chip connected to the internal circuit. It has a total volume of 4.4× 2.6× 1.75 mm³ SMD package, the smallest size of Calipile sensors ever made. The compactness of the sensor unmatched its power as compared to its predecessors. Its compactness has led to its vast integration in smart home products.
