The Kitronik Smart Greenhouse Kit for the BBC micro:bit provides an exciting way to learn about the relationship between plants and their environment. The user will learn how to monitor environmental conditions and then how to build...

Data from the wireless Go Direct Calcium Ion-Selective Electrode can give a good indication of the hardness of water (as Ca2+). The concentration of calcium is also used as an endpoint indicator in EDTA-Ca/Mg hard water titrations. The...

The Qubit EKG/EMG Sensor is designed to measure electromyograms (EMGs). These are voltage waveforms produced during muscle contraction. This sensor is a bioamplifier with high gain and excellent high frequency response, making it ideal...

The Qubit GSR (Galvanic Skin Response) Sensor measures the psycho-galvanic reflex. This reflex generates a change in skin conductivity during periods of stress, excitement, or shock and is used as a measure of sympathetic nervous system...

The Go Direct Salinity Sensor easily and precisely measures the total dissolved salt content in an aqueous solution. You have the ability to measure temperature-compensated salinity or non-temperature-compensated salinity, along with...

The Go Direct Soil Moisture Sensor uses capacitance to measure the water content of soil (by measuring the dielectric permittivity of the soil, which is a function of the water content). Simply insert this rugged sensor into the soil to...

Use the Go Direct Potassium Ion-Selective Electrode to wirelessly measure levels of potassium ions. The versatile BNC connector allows students to easily replace the electrode when it expires or becomes damaged. You need only replace the...
