The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straight forward to use. The two large exposed pads function as probes for the sensor, together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be and will result in a lower resistance, and a higher SIG out.

This is a new type of analog capacitive soil moisture sensor designed by DFRobot. Compared with the old soil moisture sensor, it has increased waterproof performance...

DFRobot Gravity: Analog pH meter pro V2 is specifically designed to measure the pH of the solution and reflect the acidity or alkalinity. It is commonly used in...

This rubber sheet is made of the same carbon-black impregnated rubber material that our conductive rubber cord uses. Traditionally it would be used for...

These SMD IC Single Hook Clip Grabbers have a small metal clip which is under spring tension that extends when squeezed. This allows them to be attached to SMD type devices quite easily. There is a round termination hole on the back of the grabber to insert a banana plug or multimeter probe.

A high-impedance passive oscilloscope probe offering 150MHz bandwidth. Provides accurate signal capture and minimal circuit loading.

Analogue meters are ideal for observing constantly varying quantities such as cyclic voltages or for speaker resonance testing. This meter has 20kO/Volt sensitivity with a colour scale and mirrored arc for parallax error reduction. Includes audible continuity tester, battery test range, and up to 10A DC current measurement.

What sensor should you use when you need to measure temperature? Most people will think of a DS18B20 temperature sensor first, but this sensor is only capable of measuring temperatures up to 125C. In order to measure temperatures greater than 100C you will need something with a greater temperature range and resistance. This is the sensor you need! We have used a PT100 resistance type high temperature probe which is often used in industrial applications. Using this probe you can measure a temperature range between 30-350C. The module itself is compatible 3.3V-5.5V supply, so Arduino, STM32 and other microcontrollers are compatible.

This is a non-contact liquid level sensor with a status indicator and adjustable sensitivity. It is especially suitable for detecting the liquid level of all sorts...

Insulation testers measure the electrical insulation strength between two conductors by applying a high voltage across them and measuring any current that flows. This is to test for “leakage” paths and insulation breakdown in electrical circuits. eg checking house wiring for leakage between active and neutral conductors or testing electrical appliances such as toasters, irons etc. This model features two resistance test ranges; 200MΩ and 2000MΩ with four test voltages on each range; 100V, 250V, 500V and 1000V. It also has auto power off to maximise battery life. The included high quality silicon test leads are designed specifically for insulation tester use and have removable alligator clip adaptors. Supplied with rubber holster and soft protective carry case. Features 200MΩ and 2000MΩ ranges Backlit LCD readout “Push to test” activation Auto power off Rubber holster Data hold High quality PVC leads Alligator clip lead adaptors Battery included Cat II 600V
