1. This circuit, based on a PIC microcontroller with a few added components, converts a sensor-based voltage into a 4- to 20-mA current loop. Shown is the circuit as originally drawn on a whiteboard.

Design of current-loop calibration device Our calibrator consists of a numerical keypad, an encoder, a microcontroller, a DAC, an ADC, current sources, and an LCD indicator (Figure 3 ). We use a ...

The idea is simple enough: just place a INA219 current sensor between the power supply and the microcontroller under observation, and record the resulting measurements as it goes about its business.

Another way to link your microcontroller to sensors and actuators is to use serial communication. Serial communication is a method of transmitting data one bit at a time, using a single wire or a ...

The I/O capabilities built into most microcontrollers make it easy to measure the analog world. Say you want to build a data logger for temperature. All you need to do is get some kind of sensor th… ...

Integrating the microcontroller, with 32kbyte flash memory,° enables the sensor to provide current, voltage, and junction temperature readout via a selectable LIN or UART output. The microcontroller ...

The system quickly processes the sensor’sanalog output signal through the analogcomparator of the microcontroller’sinternal schematic. You can make acomparison with a fixed voltage using aninternal ...

This system integrates a variety of sensors with a microcontroller, such as a ESP32, to monitor key parameters, including earth resistance, soil moisture, connection continuity, and current and ...

Researchers from Melexis, Belgium, have developed the ‘MLX91235’, an innovative current sensor, which eliminates the need for a ferromagnetic core. This breakthrough technology reduces sensor size ...
