Search Results for "voltage"

Freeware software for Raspberry PI 4B+ using GPIO and I2C connections with a hardware board with a 30 cm I2C cable (seed or qwicc) or 2m (proprietary eComet). Hardware will be available soon at http://electromaker.io. main features: max 150s measurement time, load measurement data to CSV file, measurement calibration, parallel measurement of 4 values, scale zoom in out, and move at X and Y axes For news and updates see twitter page.

This software is used to extract operational data from the EPEVER Triron solar-PV controller, including its PV power output, battery voltage, load current, device temperatute, etc. Data collection is done in two halves: a client ("solatonclient") that talks to the controller via a serial port and RS-485 adapter, and a server ("solatonserver") that stores the information in files. The "solatonclient" sends information to the "solatonserver" over the network, and because it does not need to write to the file-system itself it can be run on a small computer such as a Raspberry Pi.

...This pulses are amplified and applied to a MOSFET device that had the searching coil in series with drain. The pulse will produce a magnetic field generated by the searching coil, and becose of eddy currents, the target will produce a very low corresponding voltage at the coil terminals. The mode this signal decay depends of target characteristics ( form, type, material ) and the distance. This is the signal we need to analyze, so it is supressed by two antiparallel diodes and passed to an operational amplifier . After amplification, the analog signal is read by one of analog input of Raspberry Pi Pico board and is analized by the software. ...

This is a preconfigured version of Rasbian that communicates with Tom de Bree:s Simp-BMS hardware. Presentation of the data from the CAN-bus is presented in Node-Red through its GUI-capability. Prerequisites: 1 - Raspberry Pi 3 or newer. 1 - USBtin CAN-USB converter 1 - Simp-BMS https://www.diyelectriccar.com/forums/showthread.php/fs-tesla-vw-outlander-bms-master-198263.html https://www.fischl.de/usbtin/ See README.txt for more info.
