Circuit Design and Selection for Current Detection Using Linear Hall Sensors

Hello everyone, I am Yi. Let’s continue with the design and selection of current detection circuits. In the previous article, we analyzed the resistance method for measuring current, and found that the limitation of the resistance method is that it introduces power loss, making it unsuitable for measuring large currents. For measuring large currents, Hall … Read more

Proteus Simulation - Design of AD and DA Converters for 51 Microcontroller

Design a signal measurement and control device based on a microcontroller that has A/D and D/A functionality. The device should be able to connect to typical sensors and transmitter signals, while also outputting standard voltage/current signals. It must meet principles such as anti-interference, versatility, safety, and cost-effectiveness. The standard voltage/current signal is defined here as: … Read more
