In this video we will see the TS01 non-contact temperature sensor in the 0 to 3 Volt version of DFRobot. We will see how to easily connect it to an Arduino one together with an oled display we will be able to record the temperature of different objects that are around us without having to touch them Ideal for an industrial environment, and be able to take the temperature remotely safely.

introduction
The DFRobot TS01 IR temperature sensor is a non-contact thermal sensor, which can be used to measure the infrared intensity of the object to calculate the temperature of its surface without touching it. The built-in temperature compensation for the sensor greatly ensures the accuracy of the temperature measurement. The all-metal sensor package makes it able to protect against impacts, water, dust, etc. With stable output data, this temperature sensor can exhibit much better measurement performance than most other similar products on the market. The product has been calibrated over a wide temperature range before leaving the factory. With an operating temperature of -40oC -85oC, the sensor can be used to measure the temperature of -70oC to 380oC while providing a maximum accuracy of 0.5oC.
An optical filter (long wave pass) that cuts off visible radiant flow and near-infrared is integrated into the package to provide immunity to the environment and sunlight. Its field of view is as small as 5o, which means that for a heat source 10 cm in outer diameter, the maximum measurement distance of the sensor can reach up to 116 cm.

Measurement precision gradient diagram
- The sensor’s field of view (FOV) is 5 degrees. The target dimension and the optical properties of the IR temperature sensor decided the maximum distance between the target and the probe. The sensor field of view is shown below.
- The gradient diagram of the sensor measurement accuracy is shown below (To is the measured temperature; Ta is the temperature of the environment in which the sensor is located). Note that the temperature error only applies to a certain isothermal condition, and is only valid when the detected object is completely filling the sensor’s field of view.
