WHAT'S NEW TOP SELLERS QWIIC TEENSY REDBOARDS THING+ TUTORIALS

Easily monitor the power drawn by your AC devices without having to disconnect circuits, cut wires, or splice lines. The SparkFun Non-Invasive Current Sensor Kit gives you everything you need to safely measure AC energy consumption data all via I2C and the Qwiic Connect System. At the heart of this kit is the Qwiic-enabled ADE7953 single-phase multifunction metering IC from Analog Devices, paired with a 100A to 50mA split-core current transformer for a solderless and non-invasive sensor solution.

An Easy and Non-Invasive Way to Monitor Power Consumption

Of course, if you don't need or already have a current clamp you like to use, we also offer the SparkFun Non-Invasive Current Sensor - ADE7953 (Qwiic) as a standalone board! By simply wrapping your own clamp around your live wire and plugging it in, you can safely measure energy consumption and integrate the data directly into your microcontroller projects.

Already Have a Current Clamp? Not a Problem!

31899-Split-Core-Current-Transformer-100A-Feature-2

The Split-Core Current Transformer included in the Non-Invasive Current Sensor Kit is also available separately! This transformer is a clamp-style sensor designed to measure AC current without requiring the circuit to be disconnected. Simply open the hinged core, place it around a single current-carrying conductor, then close the clamp to create an isolated current-measurement system. With a 100A input rating and a 100A:50mA current transformation ratio, it's well suited for monitoring AC motors, lighting, appliances, power supplies, and other AC equipment.

Need a Current Clamp? STILL Not a Problem!

29260-CO2-Sensor-STC31-Feature-Corrected

Need to measure high concentrations of carbon dioxide? When standard CO2 sensors won't cut it, the SparkFun Qwiic STC31 Sensor is your solution. This powerful sensor from Sensirion is designed to measure CO2 concentrations up to a staggering 100% volume! The best part? This board just received a MASSIVE price drop!

The SparkFun Qwiic STC31 Sensor: Now Only $89.95!

Most of the time, talking to a peripheral on a microcontroller is pleasantly... basic. But every so often, the interface on the other end doesn't fit neatly into one of those boxes. That's when the NXP i.MX RT1062 inside Teensy 4.x starts to get interesting.

This transformer is a clamp-style sensor designed to measure AC current without requiring the circuit to be disconnected. Simply open the hinged core, place it around a single current-carrying conductor, then close the clamp to create an isolated current-measurement system. With a 100A input rating and a 100A:50mA current transformation ratio, it's well suited for monitoring AC motors, lighting, appliances, power supplies, and other AC equipment. Need a Current Clamp? STILL Not a Problem!
