The Candy-Ho Gas Sensor MQ-137 is engineered for precise detection of ammonia (NH3), utilizing a sensitive ceramic material (SnO2) that exhibits lower conductivity in clean air. As ammonia gas is present, the conductivity increases proportionally to the gas concentration, allowing users to convert this change into an understandable signal through simple circuitry. This sensor operates under a broad temperature range of -20 to +55 degrees Celsius and can withstand storage temperatures of up to 70 degrees Celsius, ensuring reliability in diverse conditions. Not only adept at detecting ammonia, the MQ-137 can also monitor organic amines, including trimethylamine, making it a flexible tool for various applications. It's particularly popular in home gas alarms and industrial leak detection systems due to its high sensitivity and low cost. This sensor is widely utilized in portable ammonia gas detectors and is a fundamental component in projects involving environmental monitoring and safety installations. When combined with microcontrollers like Arduino, it becomes an essential asset for developers and hobbyists focusing on gas detection solutions.

Usage ideas Ideal for home safety systems to detect ammonia leaks, suitable for industrial applications requiring gas monitoring, great for DIY electronics projects with Arduino, useful in laboratories for monitoring chemical vapors, perfect for portable gas detection devices.
