    Hello, As the title says, I would like to add some sort of antenna to the HM-10 BLE 4.2 module in order to increase it's range, so the bluetooth is discoverable at bigger distances. Looking to increase the range by 5-10 meters only, nothing big. I need someone that understands antenna design and has experience improving the range of bluetooth modules. Thank you! Marius

    Note: I'm looking for developers that have previous experience with GreenPak ICs I have a sensor that consumes ~300uA at 3.3v and I need to reduce it's power consumption by duty cycling it. The GreenPak design will need to power up the sensor, read the differential analog output, store the number of changes in a counter then power down the IC. The counter will be available via I2C for an external CPU.

    I need a test program to communicate between ESP32 (Sender) and STM32FO30F4P6 (Receiver). Please NOTE that the freelancer MUST test program using the EXACT model of the STM32 above via RS485 protocol. The code to send can be 4 digits long. On the receiver side, you can display SEQUENTIALLY 4 LEDs starting with PA5, PA6, PA7, and PA9 based on the code you send. For example 1000, 0100, 0010, 0001. That way each LED blink ON/OFF based on the information received. DO NOT SEND hex files UNLESS you are using the exact STM32. I have included the design files for your information. The winner is determined by DELIVERY SPEED and successful result. All files for STM must be written so that they can be imported via STM32Cube IDE. ESP32 file (Arduino IDE)

    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...

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.

    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.

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.

    An automatic Braking system is an intelligent mechatronic system includes an Ultrasonic wave emitter provided on the front portion of a car producing and emitting Ultrasonic waves. 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.
