To amplify the voltage from the off-the-shelf pH probe, [chris] chose an LMV358A, a high-impedance FET-input version of the venerable LM358 op-amp, so as not to load down the probe. A negative ...
Designed and Implemented an Automatic Street Light System – Developed a low-cost, energy-efficient street lighting system using an LDR sensor, LM358 Op-Amp IC, and BC547 transistor to automate light ...
The analog frontend consists of: a 1.65V voltage reference, which serves as a virtual ground point for the input, a 2x voltage divider at the input, an LM358 dual op-amp, which buffers the reference ...
