    I need to develop pressure sensor based coding for ESP32 mcu. Here, I am planning to use US9111 pressure sensor with mcp3421 ADC converter. I want to measure +5PSI to -5PSI pressure value, with auto zero calibration. When there will no pressure on the pressure sensor that must be zero value at the initial condition. It should be strictly maintain. It can be set by auto zero calibration. I want to measure pressure precisely, so you need to do the coding with exact calculation.

    The solar cable design system should take into consideration the following factors: For each of the different solar panel string cable configurations (6, 8, 12, 16, 20, 24, 28, and 32), the following design requirements should be taken into consideration: 1. Voltage and current rating of the solar panels: This information is crucial for determining the size of the cables that are needed for each configuration. 2. Cable insulation: Choose a suitable insulation material that can withstand high temperatures and UV radiation. 3. Cable length: The length of the cable between each panel and the junction box should be calculated to ensure that the correct cable size is used. 4. Number of strings: The number of cables that are needed for each configuration should be determined based on the number...

    Expert experience with home/office security controllers. Want a cheap Programmable Controller with 3G/4G enabling multiple sensors, cameras and alarms. Basically if a sensor is triggered I want the camera in the same zone to take a video and send to the cloud over 3G/4G. Its an IOT programmable controller. There are many in the market but I am looking for a price sensitive controller. Ideally want a controller that is expandable with regards to sensors/cameras/alarms etc I believe this can be sourced but if not, I'm open for someone to develop it. timeline is 7 days

    Each year food retailers and domestic air-conditioning users spend millions of dollars cleaning air-cooled condensers. Some of these condensors require more frequent servicing, some less frequent servicing. There is currently no solution available to accurately calculate the ideal cleaning time. I have designed a device that I think will be useful in helping identify when to clean condensors. A previous Freelancer has developed the PCB design and I am now seeking a Freelancer to help with the next phase of the project, building the PCB, developing the Firmware and testing the device. The design uses Sigfox, specifically the STM32WL chip as well as a number of different I/O's for example NTC temperature probes and kWh logging using HLW8012. If you are familiar with PCB de...

An Ultrasonic receiver is also placed on the front portion of the car operatively receiving a reflective Ultrasonic wave signal. The reflected wave (detected pulse) gives the distance between the obstacle and the vehicle. Then a microcontroller is used to control the speed of the vehicle based on the detection pulse information to push the brake pedal and apply brake to the car stupendously for safety purpose.

    I have a couple of holiday homes with an airco (LG s12et) and a NILAN compact P heat pump. Both systems can hear or cool the house but at this moment a lot of times the systems are working against each other because the temperature that is wished, is not synchronising. Maybe this can be done with modbus or something. The project is: -selecting the right hardware -maybe write some programming language -With the right instructions I can connect the hardware myself easily. I have attached the NILAN specifications. The LG airco specifics are easy to find online.
