Is there any posible way of measuring moisture in grain with arduino? What sensor to use? Are there any cheap sesor which can do that?

We have a bottle stickering line where bottles go over a Assembly line where the bottle goes through a product sticker (marked with a laser sensor). when the laser sensor has been triggered a new label will be pushed foward for the next bottle. This system is now broken. This works with a HMI touchscreen. The manufacturer does not respond back, so we need to make a new solution. I am thinking about a arduino/esp32 for the coding. We have relais, the wave a plc controller type: DVP-14SS2 (if even needed) We have a large steppenmotor and a label reading unit (that can be ignored if we use the sole steppenmotor). Can someone help us with this so that the sticker unit can work again. We have many more projects within our company, so it will be a longer cooperation.

We are an office with countless files. To make it easier to find these files in the future, each of them is to be fitted with an RFID sticker. About five rooms are to be equipped with a UHF reader on a Raspberry Pi. At one workstation, it should be possible to assign RFID stickers to files; this should be made possible via a web interface. It must also be possible to search for files via this web interface. This includes the name of the file, the file number and the RFID code. All UHF readers should then be addressed via a "Find file" button and search for the file (or the RFID sticker). The reader that receives the strongest signal should report that the file is in its vicinity. also we need to use a reader with a wide range, probably at lease 5 meters indoors

I looking for freelancer who can write for me sketch to Arduino. for autoleveling platform in my toy.

Develop a system of 4 lights for a garden which turn on automatically when it is dark, the user should be able to adjust the threshold this to occur. In addition to automatically turning on when it is dark, the lights must be able to be turned on or off individually by manual control. Further a user activated Monday to Sunday scheduler should be able to control all four lights in hourly segments set by the user within a custom schedule set up by the user. The hierarchy of the lighting control is thus; manual control > timer control > dark sensing. using Arduino

Hi, I need to program the LILYgo 7000G board to communicate via MQTT via LTE and wifi. It is also required to read the GPS position. Regarding the power part, it is necessary that the board goes into deep sleep consuming in general less than 50 ua/hour. To achieve that it should be possible to turn off the SIM7000G via software through the ESP32 and put the ESP32 into deep sleep. It would be necessary to see the rest of the electronic components and their power consumption.

We are looking for a programmer to build a basic plc to control a mobile dust suppression machine. There is 12 digital inputs, 8 analog inputs and 16’digital outputs in the project Flexible with hardware to suit programming language skills of applicants

However, instead of physically designing the board, the designer will create a digital representation of the PCB using specialized software. This digital file will contain all of the information necessary for the manufacturer to fabricate the physical board. During the design process, the designer must consider factors such as signal integrity, power distribution, thermal management, and manufacturability. These factors can have a significant impact on the performance and reliability of the final product. Once the digital PCB design is complete, the designer will generate manufacturing files that provide the necessary information for the manufacturer to produce the board. This includes information on the size and shape of the board, the location of components, and the routing of electric...

I have a Radar Sensor (IVS-947). Link: Datasheet: attached You need to write code for NUCLEO-F411RE board which will be connected with IVS947 radar sensor. The code should able to read number of moving objects within 80 meters, distance and their speed. The code can be developed in keil or STM32Cube. You should read the datasheet and write the connection between NUCLEO board and sensor. ** You must use Arm_CMSIS_DSP library for fast Fourier transformation which is the key for object detection. **It is needed to provide a simple GUI using matlab/python.

Hi, I have a small sailing boat which is moored in the middle of an harbour. I would like to monitor using GPRS 2G network (via Telegram) or SMS the following itens: -gps position. -temperature and humidity using the Dht11 sensor. -battery voltage. -water on the bilges. I would need also alerts for low voltage on the boat battery or high bilge water level. I have been successful in measuring the Dht11 output using WiFi and the following tutorial: However can't do it using WiFi. I'm using the TTGO T-Call V1.3 ESP32 sim800l board and dht11 sensor. Would like to continue to use the same hardware in the project. Could you please provide me a quote for the development of the code? Best Regards

Off grid solar station with an inverter connected to an external 3-pin socket need to track how many kWh's are discharged via the plug. Current thinking is tis might be a raspberry pi with a cellular modem, ideally connected to a clamp meter or similar Data sent to an IP address that can be accessed remotely in Excel or similar format. Does this sound achievable? If so, do you have any questions to be able to provide a quote. Ideal person is based in UK and able to help with hardware procurement and testing.

Looking for designing similar to TWS project. Its kind of bluetooth wireless earphone without speakers. PCB designe and sample testing

The preliminar idea of the project is to buid a device based on a STM32, that controls a 4 inch LCD screen with RGB interface, with 2 to 4 serial data signals and 4 to 8 buttons. Design using easyEDA and prototypes made by jlcpcb. All this can be modified by designer advice. The work is design and test of the PCB. More details: - The work is to design PCB and schematic - The circuit has a 12V power source - The LCD is not deciced, but has to be high bright, problably RGB888, to be decided - The serial data bus is CAN - The LCD probably has a backlight power voltage of about 15v - I decided to use easyEDA because I know it, but also to be decided - I decided to use STM32 because it has support for CAN bus and RGB888, but again to be decided Regards
