What can the addition of a negative temperature coefficient (NTC) resistor input capability bring to sensors? According to Melexis, a better detection of variations in system temperatures. The ...

Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, ...

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into the ...

Allegro MicroSystems precision programmable Hall sensor IC that includes differential Hall elements and an internal rare-earth magnet to allow it to detect ferrous targets that are not themselves ...

Texas Instruments (TI) has unveiled a range of new current sensors that simplify designs while improving accuracy. These sensors have been designed for a broad range of common-mode voltages and ...

Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...

Would you believe it, the ESP32 popular Wi-Fi and Bluetooth chip has a built-in Hall effect sensor. Espressif Systems makes the chip, and its ESP32 data sheet has nearly no mention of the Hall sensor ...
