Solenoid Valve 230V 1/2 inch 230V AC Solenoid Water Air Valve Switch (Normally Closed) – 1/2? controls the flow of fluid (liquid or air) and acts as a valve between high-pressure fluid. This liquid valve would make a great addition to your robotic gardening project. There are two ½” (Nominal NPT) outlets. Normally, the valve is closed. When a 230V AC supply is applied to the two terminals, the valve opens and water can push through. The valve switch/ sensor works with the solenoid coil which operates electronically with AC 230 volt supply. As it is a normally closed assembly, it opens the flow of fluids as soon as it is powered ON and stops/blocks the flow when the supply voltage removed. Also check Solenoid Valve 12v 1/2in designed for solar water heaters . The valve is suitable for liquid media, with a temperature range of 1 - 100 °C. It operates on a 12V DC supply, with a rated current of 0.6A and a power consumption of 8W. The valve is normally closed and has a pressure range of 0.02-0.8Mpa.

Sound Sensor Module This Sound Detection Sensor Module consists of a Microphone, resistors, capacitor, potentiometer, comparator LM393 IC, Power, and status LED in an integrated circuit. Sound Detection Module Sensor for Intelligent Vehicle Compatible With Arduino is a Single channel signal output Sensor. The output is effective to the low-level sound signal with good fidelity, When there is sound, outputs low level and signal light. It can be used for Acoustic control light, give sound and light alarm working with the Photosensitive sensor, and sound control, sound detect. (The Maximum induction distance is 0.5M). This is an Arduino compatible module. Using this module you can even measure the intensity of ambient sound. Most of the digital sound sensor module just provides digital output i.e. if the sound is present or not. But this Sound sensor module also provides an analog output voltage that is directly proportional to the intensity of the ambient sound.

Strain Gauge Module A strain gauge sensor module is a device used to measure strain on an object. This strain gauge module uses the strain gauge BF350-3AA, it has an onboard amplifier and potentiometer to adjust the measured results. This sensor module can be positively used in measuring deformation (for example, across a bridge by loading positions and effects) in engineering and in physical distortions proportional to loading or thermal environments. In the everyday world, this module can be used to applications such as gating a traffic light into a new sequence when a car on a lightly traveled side-street enters a Tee-intersection.
