Introduction

DFRobot TS01 IR Thermal Sensor is a remote non-contact sensor, which can be used to measure the infrared intensity of the object so as to calculate its surface temperature without touching. The built-in temperature compensation for the sensor greatly ensures the accuracy of the temperature measurement. The sensor's shell is made of metal which makes it able to protect against impact, water, dust and so on. Given stable output data, this temperature sensor can exhibit a much better measurement performance than most other similar products on the market. The product has been calibrated in wide temperature range before leaving the factory. With an operating temperature of -40℃-85℃, the sensor can be used to measure the temperature of -70℃~380℃ while providing a maximum accuracy of 0.5°C.

An optical filter (long-wave pass ) that cuts off the visible and near infra-red radiant flux is integrated in the package to provide ambient and sunlight immunity. As a standard, the sensor is calibrated for an object emissivity of 1. It can be easily customized by the customer for any other emissivity in the range 0.1…1.0 without the need of recalibration with a black body. Its FOV is small as 5°, which means for a heat source with an outer diameter of 10cm, the maximum detection distance of the sensor can reach up to 116cm.

In addition, we use shielding wires to reduce external radiation interference to the sensor as well to decrease its own radiation interference to the outside environment, which makes the sensor able to apply to all kinds of complicated industrial situations. At the same time, the accuracy of the product has been increased a lot.

The relation between the output temperature T(℃) and the voltage U(V) the probe output: T=U/3*450-70
