Simple water detector circuits
This simple water detector circuit utilizes alternating voltage to prevent electrode corrosion. It is easy to construct and employs N1 as a trigger Schmitt gate to generate the AC signal. When a conductive substance, such as an aqueous solution, is...
rain detector
This rain detector provides immediate notification when it begins to rain, allowing time to close windows and secure belongings. Alternatively, a molded power supply with a simple voltage regulator can be employed to reduce the voltage to 3 volts. The...
Signal Conditioning Circuit for KMI 15/x Rotation Speed Sensor
A modulated current is supplied by the integrated rotational speed sensor KMI 15/x. This current signal needs to be converted into a ground-referenced voltage signal.
The KMI 15/x sensor operates by generating a modulated current proportional to the rotational speed of...
Signal-conditioner-with-bridge
The LT1007 is capable of providing excitation current directly to bias the 350-0 bridge at 5 V. With only 5 V across the bridge, as opposed to the usual 10 V, total power dissipation and bridge warm-up drift is reduced....
rain sensor alarm circuit
A rain sensor alarm circuit is a useful device for alerting when rainfall occurs. The rain detector circuit presented is straightforward, utilizing only three components while maintaining high sensitivity to detect rain or moisture. The sensor can be constructed easily...
Simple Water Detector Circuit

Averager and Peak Hold/Extender Signal Conditioner
A signal averager circuit can be formed by an amplifier and active signal rectifier, which is implemented using two operational amplifiers in this circuit.
The signal averager circuit utilizes two operational amplifiers (op-amps) to achieve signal averaging through amplification and rectification....
Rain warning beeper
A single drop of rain on the sensing pad of this bleeper initiates an audio warning. Additionally, it can be activated by rising water levels. The circuit incorporates two transistors and features feedback through capacitor C1; however, transistor Tr1 remains...
Simple Oscillator / Pipe Locator
Occasionally, there is a requirement to create a very basic oscillator. The circuit illustrated here is remarkably straightforward, utilizing only three components.
The described oscillator circuit typically consists of a resistor, a capacitor, and a single transistor. The operation of this...
