1045_1B Phidget Temperature Sensor IR, 1045_1B


Measure the temperature of an object from a distance with this IR temperature sensor. Plugs directly into a USB port.

The late restock date for this product is due to IR temperature sensor part shortages caused by COVID-19.

Estimated Restock Date: Fri Oct 01 2021


The 1045 is an intelligent non-contact temperature sensor with a 10° field of view and a USB interface for easy connection to your computer. It takes an average of the temperature of objects placed within its cone of detection.

The 1045 outputs a continuous data flow every 32ms with an active alarm running in the background.; the temperature output data for distant objects ranges from -70°C to 380°C.

This particular revision of the 1045 has the circuitry placed on the reverse side of the board, to reduce measurement errors caused by self-heating.
