Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without actually making direct contact ...

From the looks of it, his hardware configuration is relatively simple. All it uses is a TSL261 Light-to-Voltage sensor connected to an Arduino with an Ethernet shield attached.

Depending on their implementation, these sensors can also measure the power envelope up to a bandwidth of several tens of MHz. A diode-based power sensor converts the RF signal to a DC voltage signal ...

From the looks of it, his hardware configuration is relatively simple. All it uses is a TSL261 Light-to-Voltage sensor connected to an Arduino with an Ethernet shield attached.

Designing a sensing application involves circuitry for amplification of a sensor signal, its conditioning and, in most cases, conversion into digital form. This is achieved conventionally by using ...

Genetically encoded voltage sensors are coming of age, but their use still poses challenges that must be addressed from multiple angles.

The ACPL-C87B/C87A/C870 voltage sensors are optical isolation amplifiers for voltage sensing.

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.
