The IDT SGAS701 is a solid-state chemiresistor sensor designed to detect hydrogen in air. The sensor uses an integrated heater with highly sensitive MOx material tailored for detection of hydrogen. The chemiresistor sensors of IDT’s SGAS family are based upon the principle that metal oxide materials undergo surface inter- actions (physisorption and chemisorption) with gas molecules at elevated temperatures, resulting in a measurable change in electrical resistance. As these materials are poly-crystalline (i.e., composed of multiple grains with distinct grain boundaries), the
adsorbed gases have significant electronic effects on the individual grains. These gas-solid interactions result in a change in electron (or hole) density at the surface (i.e., a space charge forms), which in turn changes the electrical conductivity of the oxide. IDT has developed a set of nanostructured gas sensing materials with excellent sensitivity and stability. Applications:
  1. Leak Detection
  2. Gas Concentration Detection
  3. Breath Detection

Specifications:

  1. High sensitivity to low hydrogen concentrations (<10 to 1000 ppm)
  2. Fast response time (<15 seconds at 100ppm)
  3. Environmental temperature range of -20°C to 50°C
  4. Environmental humidity range of 0% to 90% RH,
    non-condensing
  5. Low dependence on flow rate
  6. Rugged, reliable sensor based on IDT’s exclusive technology
Note: For more info., refer to datasheet in the ATTACHMENTS section.

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
