Read moreUnder & Over Temperature Sensor AC Switch for Heater, Fan, and Airflow Controller The TMP01 is a temperature sensor that generates a voltage output proportional to absolute temperature and a control signal from one of two outputs when the device is either above or below a specific temperature range. Both the high/low temperature trip points and hysteresis (overshoot) band are
Read moreThe UAA2016 is designed to drive triacs with the Zero Voltage technique which allows RFI-free power regulation of resistive loads. Operating directly on the AC power line, its main application is the precision regulation of electrical heating systems such as panel heaters or irons. A built-in digital sawtooth waveform permits proportional temperature regulation action over a +/-1°C band around the
Read moreClap switch/Sound-activated switch designed around op-amp, flip-flop and popular 555 IC. Switch avoids false triggering by using 2-clap sound. Clapping sound is received by a microphone, the microphone changes the sound wave to electrical wave, which is further amplified by op-amp. 555 timer IC acts as mono=stable multi-vibrator then flip-flop changes the state of output relay on every two-clap sound.
