This report introduces the wireless sensor interface project of the SEP group project. The objective of the project is to develop a system to collect data from sensors, and to transmit this data wirelessly to a node which passes the data to a PC. Wireless transmission methods have been investigated, and it was decided that a proprietary protocol would be designed. A TDMA based protocol has been designed. Sensor tests have been performed, and the protocol has been designed and detailed in this report. This report also discusses the progress made to date on the project, and proposes a timeline for the completion of the projects

specs of the desired project are below. It should have 24V 2A 48W continuous output. It should have OVP, UVP, OPP, SCP. It should have lowest DC-link capacitor possible. It should have input power-factor above 0.9. It should have output ripple voltage less than 100mVpp. It should have low cost PWM controller with external power switch. It should be compliant with global EMI/EMC standards. It should be compact as possible on single PCB.

Main idea. To have multiple buttons around a office/home and when someone presses it a blink/signal will occur on the units like a common signal for an event. To ACK the signal everyone will need to press the button to confirm. This is a MVP concept design and I will add more functionality later. The only HMI will be a button and a LED (maybe RGB) so all info will be via that interface I will do all HW myself and want a fully functional software delivered. Assume the freelancer have this stuff at home to laborate and test the HW setup for a secure and proper debugging.

Hi, i need a same day turnaround for a program for a linear actuator contoller using esp32-wroom32D. I have a custom pcb with the esp, relays, power, eol sensors and led/sounder output, and would like it coding so that a bluetooth remote (used for a phone camera shutter) can trigger the actuator to extend or retract. I have been let down by my engineer and need to get this running today. Thanks!

Hello, I need a schematic with similar features to this video: This video has a schematic in the description. But instead of a boost converter, I'll need a buck converter, and I'll use an 11.1v lipo battery. The schematic needs to be done in the easyeda. Additionally, I'll add an Attiny85/84 and some sensors and I'll tell the connections for the sensors with Attiny. Please tell me your best quote. Thanks.

We are an IoT company and are seeking to contract with a wonderful software developer for our technology. The following is a description of the project. Electronic modular 32x128 LED sign driven by ESP32 microcontroller with codebase written in C / C++ needs functionality added to allow loading fonts from flash, switching fonts, and designing fonts using a PHP interface. You will be working with the original developer who has 25+ years of experience and can suggest approaches. Must be familiar with C, C++, PHP, and the use of git. Previous microcontroller experience a plus. Looking forward to hearing from you!

first the ultrasonic will detect the water level, if satisfied then start an internal timer and turn on the second relay for 5 minutes. Next, the proximity sensor will detect the distance of the fluid and control the third relay. Lastly, a tds sensor will tell whether to open the fourth relay or open the first relay whereby activate the ultrasonic sensor again

I am looking for an AVR/ESP programmer who will help on the code to generate an 8 pulses signal at various frequencies and various duty cycles using ESP 32 and ATMEGA328P based arduino NANO. The frequency varies from 200Khz to 1Mhz. (There is a table for the various signal pulses on the PDF files). The 8 pulses are to drive a PNP transistor! An image of a pulse we are looking to achieve. The signal in Yellow is the result we are looking for. I have other tasks as well!! Can you do it?

1. This is a project based on a circuit board. I will provide the schematic diagram later. In the picture you see a BLE module, but I will try to add one more. 2. The connector on the upper left has 4 input, 12v, gnd, CAN+ and CAN- 3. The 4 connectors on the bottom is pretty much the same, it control 4 identical components. Each connector has 6 wires: Gnd, two output for dc motor, ws2812 data, 5v, and a switch trigger. 4. Whenever a switch is pulled to ground, it will trigger the motor to pull for 1 second. 5. Whenever a motor is pulled, the ws2812 will start to light up. 6. After 20 seconds, the motor should reverse back. And the Ws2812 strip should light off. 7. Whenever a certain CAN signal is received (will be provided), all the 4 motor should pull for a second. All 4 ws282 strip will...
