TEMP&HUM ±5%RH for RASPBERRY PI PICO

TEMP&HUM ±5%RH for RASPBERRY PI PICO and PICO2

TEMP&HUM ±5%RH for Raspberry Pi Pico and Pico2 is a compact and easy-to-use environmental sensing module designed for temperature and relative humidity measurement with Raspberry Pi Pico and Pico2 platforms. The module combines two commonly used digital sensors, the DS18B20 temperature sensor and DHT11 temperature and humidity sensor, providing a simple and flexible solution for embedded environmental monitoring.

The DS18B20 provides digital temperature measurement through a reliable 1-Wire interface, while the DHT11 provides both temperature and relative humidity measurements through a dedicated digital data interface. Using two different sensing technologies allows the module to be used for comparison, testing, and different temperature and humidity monitoring applications.

The DS18B20 communicates with the Raspberry Pi Pico or Pico2 using a single GPIO pin and supports digital temperature measurement without requiring an analog input. The DHT11 uses a separate GPIO connection for temperature and humidity data, making both sensors independently accessible from the MicroPython software.

The module is designed as a simple and flexible sensor interface that can be connected directly to Raspberry Pi Pico or Pico2 development boards. Its compact design and minimal external component requirements make it suitable for rapid prototyping, sensor testing, data acquisition, and integration into custom embedded systems.

MicroPython example programs can be used with Raspberry Pi Pico/Pico2 to read temperature from the DS18B20 and temperature/humidity data from the DHT11. The measured values can be displayed, compared, logged, transmitted, or used to control other devices according to the application requirements.

The TEMP&HUM ±5%RH module is suitable for temperature and humidity monitoring, environmental data logging, sensor comparison and testing, IoT projects, smart-home systems, greenhouse monitoring, weather stations, educational projects, and Raspberry Pi Pico/Pico2 embedded applications.

Additional Notes and Information

To run the provided MicroPython example for the TEMP&HUM ±5%RH for Raspberry Pi Pico and Pico2 module, install and use the Thonny IDE with your Raspberry Pi Pico or Pico2.

1. Install Thonny IDE on your computer.

2. Connect the Raspberry Pi Pico to the PC using a USB cable.

3. In Thonny, select MicroPython (Raspberry Pi Pico) as the interpreter.

4. Open the provided `main.py` example file.

5. Save the file to the Raspberry Pi Pico (File → Save As → Raspberry Pi Pico).

6. Press Run (F5) or restart the board.

After uploading, the main.py file will automatically execute on every board reset. The program initializes the DS18B20 and DHT11 sensors, reads the temperature and relative humidity measurements, and displays the measured values through the MicroPython console.

The DS18B20 provides digital temperature measurement using the 1-Wire interface, while the DHT11 provides both temperature and relative humidity data through its digital interface. Using both sensors allows temperature measurements to be compared between the two devices.

The example code allows immediate verification of the temperature and humidity measurements after startup and provides a simple starting point for developing environmental monitoring, data logging, IoT, automation, sensor comparison, and other embedded applications.
