SKU: AF-259 · MPN: 259

This is a Lithium Ion and Lithium Polymer battery charger based on the MCP73833. It uses a USB mini-B for connection to any computer or 'USB wall adapter'. Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-volta...

SKU: SF-SEN-13715

This is a stainless steel, Type-K Thermocouple probe. A thermocouple works by taking two wires made of dissimilar metals, connecting them at the two ends, and making a temperature gradient between one end and the other (a ‘hot’ end and a ‘cold’ one). Once this is achieved, a voltage potential is ...

SKU: SF-COM-30222 · MPN: COM-30222

This compact resistor network packages eight individual 10k Ohm isolated resistors into one 16-pin 2506 surface-mount component. It is a handy way to save board space when a design needs several identical resistors close together.Each resistor element is rated for 63mW with a ±5% tolerance, makin...

SKU: LB-LS4690-50CM

A waterproof DS18B20 digital temperature probe with a 0.5m cable and XH2.54mm connector. Ideal for monitoring temperatures in wet or harsh environments including aquariums, hydroponics, brewing, and outdoor weather stations. The DS18B20 is a popular one-wire digital temperature sensor that commu...

SKU: DF-SEN0496

This full-scale oxygen sensor uses an original AO2 CiTiceL electrochemical probe to measure oxygen concentrations from 0–100%Vol via I2C digital output. A built-in calibration algorithm on the signal board supports single-point or double-point calibration for accurate readings in demanding enviro...

SKU: DF-SEN0233

A multifunction air quality monitor that measures particulate matter (PM2.5), formaldehyde concentration, temperature, and humidity. It uses laser scattering to detect suspended particles in the air, an electrochemical probe for formaldehyde detection, and an integrated sensor for temperature and...

SKU: AF-3984 · MPN: 3984

For precision temperature sensing, nothing beats a Platinum RTD. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is actually a small st...

SKU: AF-4308 · MPN: 4308

A flexible electric heating pad made from stainless steel fibre fabric. Apply 5–12V DC and it warms up — temperature varies with voltage. Lightweight and flexible enough to wrap around objects or integrate into wearable projects. Essentially a large flexible resistor, it can be driven with PWM v...

SKU: AF-386 · MPN: 386

The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing t...

SKU: AF-6379 · MPN: ADA6379

Measuring stretch and movement can be tricky, and this conductive rubber cord gives you a simple, hands-on way to do it. The cord is made from carbon-black impregnated rubber, with resistance that increases as it is pulled longer.In its relaxed state the cord is around 350 ohms per inch, and as i...
