The **M5TS-05-R** is a high-performance, non-contact infrared (IR) temperature sensor module, typically developed by manufacturers like Omron or specialized sensor providers. It is designed for thermal management, human presence detection, and industrial monitoring. --- ### ## Technical Specifications The core of the M5TS-05-R is its ability to convert thermal radiation into a digital temperature reading without physical contact. | Feature | Specification (Typical) | | :--- | :--- | | **Detection Method** | Thermopile (Infrared) | | **Object Temp Range** | -20°C to +200°C (Application dependent) | | **Communication** | I2C (Inter-Integrated Circuit) | | **Operating Voltage** | 3.3V to 5.0V DC | | **Field of View (FOV)** | ~5 to 10 degrees (Narrow beam) | | **Output Format** | Digital (16-bit or 24-bit data) | --- ### ## Key Electronic Components & Architecture 1. **Thermopile Sensor Element:** The heart of the module. It consists of a series of thermocouples that generate a tiny voltage when exposed to infrared heat. 2. **Signal Conditioning (ASIC):** Because the raw voltage from the thermopile is extremely low (microvolts), an internal **Application-Specific Integrated Circuit (ASIC)** amplifies the signal and performs Analog-to-Digital Conversion (ADC). 3. **Built-in Reference Thermistor:** To calculate the *Object Temperature*, the sensor must also know its own *Ambient Temperature*. A built-in thermistor provides this reference, allowing the internal logic to subtract ambient heat from the total detected radiation. 4. **Optical Lens/Filter:** The "R" in the part number often signifies a specific lens or range configuration. The module includes a silicon filter that blocks visible light and only allows infrared wavelengths (typically 5.5µm to 14µm) to pass through. --- ### ## Pinout and Integration The M5TS-05-R usually follows a standard 4-pin configuration for easy integration with microcontrollers like Arduino, ESP32, or STM32. | Pin Number | Label | Description | | :--- | :--- | :--- | | 1 | **VCC** | Power Supply (3.3V/5V) | | 2 | **GND** | Ground | | 3 | **SCL** | I2C Serial Clock Line | | 4 | **SDA** | I2C Serial Data Line | --- ### ## Application Use-Cases * **Medical:** Non-contact forehead thermometers. * **Industrial:** Monitoring overheating in circuit breakers or motor bearings. * **Home Automation:** Human presence detection for HVAC control. * **Office Equipment:** Monitoring fuser temperature in laser printers. ---
