...who can help me? I have a Omron ZX1-LD300A61 or Panasonic HG-C1400 laser displacement sensor, and a DM542 driver + motor. I want the module to set a fixed height, say 25m from sensor to base. And when I put something under the sensor, say 10cm high object, and I need thesensor to raise the tower 10cm up so it is still 25cm from sensor to object. When I remove object it goes down. Ideal is to add 3 buttons. One UP button, when pressed motor turns up One DOWN button, when pressed motor turns down One for Auto, you activate the sensor for raising/lower the tower to 25cm or whatever it is saved in memory. So it needed to be manually set to a height. Maby add a 4th button for save heigh when programming sensor? That is you use up and down buttons ...

I need to create a 24ghz radar sensor using FMCW triangular modulation to detect people and cars when the sensor is stationary and mobile. It is important to detect people and cars when stationary and mobile while filtering out stationary objects. Once a person/ car is detected, it will activate a "flat coin vibration motor". What will be powering the device is a lipo battery, I need an LED to be red when the battery is less than 20% and green when above 80%. I need CUSTOM pcb antennas for the radar sensor to be on the pcb with the micontrollers controlling the sensor, vibration motor, battery, and LED. I need PCB design, antenna design, and software done. This device needs to be as compact and light weight as possible. Attached below is a Garmin Vari...

I need someone experience in Arduino programming. The job is to create the firmware for an Arduino Nano with multiple simple sensors (LEDs, temperature, buttons, EEPROM, RTC, etc...). You need to be able to code object-oriented (a class for each sensor) and know how to have multiple process running (using timers or interrupts, no delays or halting the MCU). It can also help if you know a lot of open-source libraries that can be used/adapted. Detailed specification will be provided to selected candidates.

Hi guys, Looking for someone to complete my pcb design. I have an 90% completed circuit schematic file for ESP32-S3 and GD32E503RET6 which needs to be routed and error corrected for PCB fabrication. The board contains barometer ic , Gyroscope+accelerometer ic,shunt resistor. Would send the .sch file and footprints and share more details there.

Attached is a factory IO scene, that I would like to simulate it using open plc. The scene creates 3 boxes of a different colors (green, grey, and blue). They moved down on the main conveyor belt. conveyor belts also have vision sensors. 3 pick and place machines should grab them based on the output of the vision sensor and place them on another belt. The program also needs to count the number of each box. also needs to indicate how things are going with stack lights. Green light means grabbing more items red means missing items yellow means doing what it suppose to do free open plc: factoryy io( 30 days free):

I would like to create a temperature and humidity sensor based on the esp12f and the SHT31 chips alimented by 2 AA batteries. The components must ALL be on one side of the PCB but the PCB can have tracks on two sides. The PCB should not cover the esp12f antenna and the SHT31 should be placed far away from the antenna. The size of the PCB should be kept to a minimum. The cables of the battery holder are soldered by hand to the PCB. The deliverable are the PCB designs and the BOM in Gerber format and the associated source files. Here are the pin connections for the ESP12F: - GPIO16 should be connected to RESET. - EN/CH_PC pin should be pulled-up with a 10kOhm SMD resistor. - GPIO15 pin should be pulled-up with a 10kOhm SMD resistor. - There should be a tiny push-button connected be...

Budget: Not more than $450 This is a simple project where you are required to modify a Graph neural network/Graph deviation network model that is based on () The github model is an anomaly detection model. The steps include: 1. Sensor Embedding: uses embedding vectors to capture the unique characteristics of each variable 2. Graph Structure Learning: learns a graph structure representing dependence relationships between variable 3. Graph Attention-Based Forecasting: forecasts future values of each variable based on a graph attention function over its neighbors 4. Graph Deviation Scoring: identifies deviations between actual and predicted values using threshold calculation Modification on the model: Apply one of the below to set thresholds and select the best

The purpose of this project is to develop an electronic design for an early stage proof-of-concept prototype motion detector for a specific application. A successful design will successfully integrate three independent Senba Sensing Tech. BS-612 smart PIR modules with an Adafruit Feather M0 microcontroller development board. The integration will allow the sensitivity of the PIR modules to be independently controlled via AnalogWrite PWM. The scope of the project is delivery of a working schematic design. No Arduino code is required. No PCB layout is required. Acceptance will be based upon the results of breadboarding the circuit and confirming functionality. This project will be the first in a series of many electrical engineering projects that will ramp up as product develo...

Hello! I'm using an esp8266 to transfer data from a sensor (Ezo Hum) to InfluxDB and control room humidity by turning a humidifier on/off. i got 2 problems so far: 1. The data on influxdb is not visible on mobile phones, so i cant check values when im on my mobile. the moment the sensor checks the humidity every few seconds, if the values is under 70% the humidifer turns on till it reaches 90% and then goes to sleep for a couple minutes before checking humidity again. if Humidity is above 70% nothing happens. Problem is, that the humidity at the moment is constantly above 75% outside so the humidifier never turns on but i need the spikes with 90%. I need a code to check humidity and if its been above 70% but under 80% for the past 20minutes it should turn the humi...

We have two tasks to be completed in this project, this small system will be integrated into a bigger system that is controlled by PLC (24V). 1) SMS alert when a sensor gets HIGH 2) Change the video on the display (that is continuously playing a different video) when a HIGH signal is received from the PLC. We know two solutions to achieve this, there is a HDMI shield for arduino available in the market that can be used to connect to the display and control it. Another solution is that we can use Raspberry Pi Zero and connect the display through HDMI and control the display with a code. Please only experienced people bid on this project and respond with "PLC" in your bid. Thank you.

...will never be anything legitimate from all analysis I have done) If it finds any patterns like that the range needs issued to an available signal generator for output. Each signal generator should randomly sweep and jump frequencies in their ranges switching between AM and FM randomly based on a random seed generated by an instrument other than the clock. I suggest adding Temperature/barometric sensor that should be queried every 30 seconds for a new random seed. Ranges above 1ghz must always be blocked if possible in the ranges around 1.380-1.070 and 1.480-1.500 and 1.255-12.75, but the SDR should always be checking for all detected ranges to change. If you do manual analysis to find ranges they will resemble a Fence or barcode in appearance. Ranges should be carefully spread a...
