This schematic diagram shows a water level sensor/detector/monitor circuit. An alarm is also featured in this circuit. Any fluid with a resistance under 900K between the maximum separation distance of the probes will trigger this circuit. A 4050B CMOS hex buffer is used on this circuit that is working at 5 volt supply. The 10M resistors connected between buffer input […]

This is a TMP01 temperature out-of-range warning circuit. This circuit is used to generate a temperature out-of-range warning signal. This circuit is usually used in sensitive equipment calibrated to work over a limited temperature range. This circuit can be done by connecting the two open-collector outputs of the TMP01 together into a wired-OR configuration. Here is the schematic diagram of […]
