It consists of two tanks, one for supply and one for control. The water level in the control tank should be adjustable for two different levels. One high and one low. Levels are determined with a sonic sensor and are adjustable. Time at each level is adjustable. Levels are to be maintained at each level. Two pumps are involved, which run off arduino relay board. Pump #1 brings water into the controller tank from the supply tank, and pump #2 pumps from the controller back to the supply tank. No level sensor is needed for supply tank Program can be set for one day with repeat opti...
WE need an IOS app that can read remote inputs and calculate engine rpm (up to 4000), ground speed (up to 50 mph) and distance traveled(up to 400 feet) and log to a data base. Distance and speed is calculated from ground driven sensor. (similar to sensor on abs brakes of automobile) App must be able to send and recieve the database info to another IOS device up 400 feet away. App must also be able to read one camera used as backup camera and another camera used to read QR codes that are 10 feet away. QR code will identify record to use from data base for identification.

GUI must be easy to operate and attractive design Software is kiosked so computer c...
We require an SMTP client capable of communicating with secure email hosts (STARTTLS/TLS/SSL) via a Telit LE910 module. The client should be based around an STM32 microcontroller. The interface to our current project is via a UART and if needed a maximum of 4 GPIO. Communication to our current project is on a one second polling basis. Low power consumption is a major part of the project and so processor frequency and stop mode usage should be utilised to best efforts. Any certificates required should be able to be imported through the UART. As an extension to the project, a simple GUI to retrieve the required certificates from a Windows based PC.

Only contact us if you are in possession of a HackRF or any other RTL-SDR device. We are in the need to capture the identifiers (packets) from vehicle's Tire Pressure Monitoring Systems (TPMS). Each latest device with a TPMS transmits every x-time a packet - we need to capture this. The data transmitted consists primarily of a sensor ID, the tyre pressure, the tyre temperature and a checksum (other status bits are also transmitted). The software must be developed for a specific Ubuntu version and operational on Raspberry Pi. Budget $500 We prefer if you already have experience with this.

I want to build a system that can measure the movements of fingers based on the EMG signals. Ideally the system should be able to diffrentiate between the fingers and can records movements of multiple fingers simultaneously. If that is not possible than it should be atleast record the signal so that we can do analysis on that afterwards. The price can be negotiable but there will be milestone for every steps that we will discussed later. If you have read the description till here type SIGNALS before bidding.

Hi all, I need to write data from an RS485 device to a Webserver through the device Usriot TCP232-410s. I have a RS485 sensor connected to this device, and I want to write data in a database in my server. Is important to know how the device works:
I need a control system for the liquid level in a tank. Use two sensors (wires); one at the bottom and one at the top. Once the liquid touches the two sensors and stays like that for 5 seconds, the Arduino card should be able to "read" it and turn a 5V pump on. And the other way around for turning off the pump. Potentially usable additaments are welcome. Now, think about this 1-tank but for 8 independent tanks and assemble it the simplest and most elegant way you can. I will require the circuit diagram, the program to feed into Arduino (with comments for mortals), and the list of items to buy on amazon.

This project is based on ESP8285 microcontrollers and programming should be done in Visual Studio Code (PlatformIO) Background: This is supposed to be a monitoring system. It involves detecting sensor values at multiple locations (at least 25, with more to be added, on demand). Each sensor location is connected to an ESP8285 wifi board on UART1 (soft serial). All of the 25 individual wifi modules will connect to a central hub - which is another ESP8285 module. This central hub will be connected to a cloud server through a broadband router. It will send the data of all the 25 sensors to the cloud server. The cloud server will also reply back some data which needs to be transmitted back to the 25 sensor modules. Based on this data, the individual 25 sensors wil...
