Description

The HYDROGEN Click utilizes an MQ-8 semiconductor gas sensor with a tin dioxide (SnO2) sensing layer. In clean air, the sensor’s conductivity is low; it increases proportionally with rising hydrogen gas concentration. The board includes a potentiometer to adjust the sensor circuit’s load resistance, allowing calibration for specific environmental conditions and ensuring accurate ppm readings.

Designed for the mikroBUS standard, this Click board provides a plug-and-play solution for rapid prototyping on compatible host boards. It requires a 5V power supply for optimal sensor heater operation, though the logic is compatible with 3.3V systems. The sensor requires an initial 24-hour preheat period for stabilization before precise measurements can be taken.

Key Features

  • High-sensitivity MQ-8 semiconductor hydrogen gas sensor
  • Analog voltage output proportional to gas concentration
  • Integrated calibration potentiometer for field adjustment
  • Robust mikroBUS form factor ensures reliable mechanical and electrical connection
  • Wide operating voltage range supports 3.3V and 5V logic systems
  • Optimized performance-to-cost ratio for prototyping and educational use

Frequently Asked Questions

What is the output signal type of the HYDROGEN Click board?

The HYDROGEN Click provides an analog voltage output via the AN (OUT) line on the mikroBUS connector. The output voltage varies proportionally with the detected hydrogen gas concentration, allowing it to be read directly by an MCU's ADC pin for ppm calculation.

How do I calibrate the sensor for my environment?

Use the on-board potentiometer to adjust the sensor circuit's load resistance. For precise calibration, expose the sensor to a known hydrogen concentration or clean air baseline after a mandatory 24-hour preheat period. The potentiometer fine-tunes the sensor's sensitivity and output range.

What power supply does this Click board require?

The board is designed for a 5V DC supply to properly power the MQ-8 sensor's internal heater. While the logic levels are compatible with 3.3V systems, the power input must be 5V for the sensor to operate correctly and achieve its specified detection range and sensitivity.

Is this sensor compatible with Arduino or Raspberry Pi?

Yes, but it requires a host board with a mikroBUS socket or a compatible adapter. You can connect its analog output to any microcontroller ADC pin (e.g., on an Arduino). Ensure your host board provides the required 5V power supply via the mikroBUS VCC line.
