Connection Diagram

• TS01 outputs 4~20mA standard industrial current signal, a current to voltage converter is highly recommended when you want to use MCU to read the value.
• The power supply of TS01 is 7.5-36V.

Sample Code

void setup() {
Serial.begin(115200);
}

void loop() {
unsigned int ADC_Value = analogRead(A3);
float i=(double)ADC_Value/(204.8*0.12);
float j=(i-4)/16*340-70;
Serial.print(i);
Serial.print("mA, ");//printed current value
Serial.print(j);
Serial.println("\u2103");//printed temperature value
delay(100);
}

Result

Gradient Diagram of Measuring Accuracy

• The field of view(FOV) of the sensor is 5°. The target dimension and the optical properties of the IR temperature sensor decided the maximum distance between the target and the probe. The field of view of the sensor is shown below.

• The gradient diagram of measuring accuracy of the sensor is shown below (To is the measured temperature; Ta is the temperature of the environment the sensor locates in). Please note that the temperature error only applies to a certain isothermal condition, and it’s only valid when the detected object is fully filling in the FOV of the sensor.
