M5Stack TMOS PIR High Sensitivity Infrared Sensor Unit STHS34PF80 for IoT Intell

Product Description

Product features

1. STHS34PF80 Infrared Sensor: The TMOS PIR Unit is powered by the STHS34PF80 chip, providing high-sensitivity infrared detection for precise presence and motion sensing.

2. 80-Degree Field of View: With an 80-degree field of view, the TMOS PIR Unit offers a wide detection range, allowing it to monitor a broad area for motion and presence.

3. I2C Communication: The sensor communicates with M5 devices via I2C with a default address of 0x5A, enabling easy integration and data transfer with compatible systems.

4. Adjustable Gain Modes: The unit supports adjustable gain modes to optimize sensitivity based on application needs. The default high sensitivity mode may cause saturation, while the wide mode avoids saturation with a shorter detection distance.

5. Programmable Output Data Rate: The TMOS PIR Unit allows for a programmable output data rate ranging from 0.25 Hz to 30 Hz, providing flexibility in how frequently data is sampled and updated.

6. Infrared Sensitivity and Accuracy: The sensor has an infrared sensitivity of 2000 LSB/°C and an accuracy of ±0.3°C, ensuring reliable temperature and motion detection.

7. Compact Design: With dimensions of 32*24*8mm, the TMOS PIR Unit is compact and easily integrates into various systems and applications.

**High-Sensitivity Detection**

The TMOS PIR Unit, featuring the STHS34PF80 chip, excels in high-sensitivity infrared detection, making it ideal for applications requiring accurate presence and motion sensing. Its 80-degree field of view ensures comprehensive coverage, while its programmable data rate and adjustable gain modes provide flexibility for diverse use cases.

**Versatile Applications**

This unit is suited for a wide range of applications, including alarm and security systems, smart lighting, furniture automation, and IoT solutions. Its capability to detect both stationary and moving objects with high sensitivity makes it a valuable tool for various automation and monitoring tasks.

**Integration and Calibration**

The TMOS PIR Unit integrates seamlessly with M5 devices via I2C communication. Users can adjust gain modes to prevent sensor saturation and calibrate temperature settings to accommodate different operating environments, ensuring optimal performance across varied conditions.

SpecificationsSchematicDimensionsProduct ComparisonNote:

1. Set the TMOS gain mode:

Default gain mode: High sensitivity, but it may cause sensor saturation. Saturation can lead to delayed updates of the motion/presence detection flag;

Wide mode: Shorter detection distance, but avoids sensor saturation.

2. Sensitivity to temperature differences: The output signal of the TMOS sensor is very sensitive to the temperature difference between the sensor's own ambient temperature and the ambient temperature of the measurement room. This temperature difference can affect the sensor's measurement.

3. Power-down mode settings: When the device is in power-down mode, the register resets to its default value each time the device is started or restarted. Calibration temperature needs to be reset. Therefore, if the application requires covering a wide operating temperature range and the temperature difference between the room and the sensor's thermal coupling environment, the user needs to set the wide mode when the device starts.
