Here is a gas leak detector circuit that detects the leakage of LPG gas and alerts the user through audio-visual indications. The circuit operates off a 9V PP3 battery. Zener diode ZD1 is used to ...

The performance of even the best sensor can be degraded by poor design of the signal conditioning circuit that interfaces its output to the digital processors at the heart of the system. Equally, over ...

The sensor front ends represent all the sensor-specific driving circuitry and signal-conditioning circuitry, as already described in the context of the different transducers.
