The Figaro TGS1820 is a compact, low-power consumption MOS-type gas sensor engineered for the detection of acetone. Its sensing element utilizes a sintered metal oxide semiconductor material on a noble metal coil, where changes in electrical conductivity due to gas adsorption are measured.
This sensor exhibits high sensitivity and selectivity specifically for acetone, making it suitable for applications such as acetone detectors and breath acetone testers. It is designed to have low interference from ethanol and hydrogen, ensuring more accurate acetone readings. The TGS1820 provides a quick response time, allowing for rapid detection.
Typical sensitivity characteristics show a sensor output voltage difference (ΔVOUT) that increases with acetone concentration. The sensor operates by applying a circuit voltage, which also serves as heater voltage, and measuring the output across a load resistor in a Wheatstone bridge configuration. The compact size and low power consumption make it an efficient choice for portable devices.
