The TS01 non-contact sensor high temperature alarm is a system designed to detect and alert about dangerous temperature conditions in various environments. This system uses the TS01 sensor, which is capable of measuring temperature without the need for physical contact with the object or environment to be monitored.
The TS01 sensor uses infrared technology to capture the thermal radiation emitted by the object and convert it into an accurate temperature measurement. This enables contactless detection, which is especially useful in situations where direct interaction with the object is impractical or undesirable.
When the TS01 sensor detects that the temperature has reached or exceeded a predefined threshold, it triggers an audible or visual alarm to alert users to the high temperature situation. This allows for a quick and efficient response to potential overheating risks, thus protecting the integrity of equipment, installations and, in some cases, the safety of people.
Technical Deep-Dive: TS01 IR Thermopile & Boltzmann Forensics
- The Contactless Thermal Logic: The TS01 utilizes an internal thermopile to capture long-wave infrared radiation. Its $0-3\text{V}$ analog output maps to a massive $-70^{\circ}\text{C}$ to $380^{\circ}\text{C}$ range. The diagnostics focus on the "Inverse Square Law" vs. specific Field-of-View harmonics; with a $5^{\circ}$ FOV, the system ensures precision detection of a $10\text{cm}$ target at a distance of $116\text{cm}$, providing absolute operational-safety forensics.
- Emissivity & Compensation Analytics: Different materials emit IR radiation with varying efficiency $(\epsilon)$. The TS01's internal temperature compensation logic adjusts for the ambient sensor-body temperature $(Ta)$ relative to the object temperature $(To)$, ensuring a $\pm 0.5^{\circ}\text{C}$ accuracy gradient in isothermal conditions.

Engineering & Implementation
- Signal-Integrity & Shielding Forensics:
- Industrial-Grade EMI Mitigation: The TS01 probe is encased in a metal package and utilizes shielded cabling. Forensics focus on reducing parasitic radiation-interference from nearby high-switching inductive loads. The diagnostics ensure that the $0-3\text{V}$ analog bit-stream remains rock-steady, preventing false-positive alarm triggers.
- PCB-Level Integration Sophistication: The implementation utilizes a custom-etched PCB. Forensics focus on the ground-plane stiffness and trace-separation for the I2C lines to prevent capacitive-coupling harmonics between the high-speed OLED clock and the analog sensor-feed.
- HMI Alert-Logic Aesthetics:
- The software architecture features a dual-threshold alert system. Forensics involve real-time polling of the analog input, triggering specialized visual "Overheat" graphics on the OLED when the threshold $(e.g., > 100^{\circ}\text{C})$ is reached, providing a professional-grade safety interface.
Sensor TS01
INTRODUCTION
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 its surface temperature without touching it. Built-in temperature compensation for the sensor greatly ensures the accuracy of temperature measurement. The all-metal package of the sensor makes it capable of protecting against impact, 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 in a 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 visible and near-infrared radiant flux is integrated into the package to provide immunity to ambient and sunlight. Its field of view is as small as 5°, meaning that for a heat source of 10 cm outer diameter, the maximum measuring distance of the sensor can reach up to 116 cm.
In addition, we use shielding cables to reduce the external radiation interference to the sensor as well as to decrease its own radiation interference to the outside environment, which makes the sensor can be applied to all kinds of complicated industrial situations. At the same time, the accuracy of the product has been greatly increased.

Measurement accuracy gradient diagram
The field of view (FOV) of the sensor is 5°. The dimension of the target and the optical properties of the IR temperature sensor decided the maximum distance between the target and the probe.
The gradient diagram of the sensor measurement accuracy is shown in the image 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.
