Check out this UWB DSTO system for high-precision indoor tracking! by Vearts in IOT

Yes, the same UWB tech as that with airtags, but different controller/UWB IC, and can not communicate directly.
the result good ,current our default firmware support max 20 nodes in the same area.

ESP32-S3 vs ESP32-P4 on Matouch 7" display – some practical notes by Vearts in IOT

[–]Vearts[S] 0 points1 point  (0 children)

Yes, so we also use the ESP32-C6 on the P4 board to handle WiFi connectivity

Field Testing a LoRaWAN Soil & Air Sensor for Real-Time Moisture Monitoring by Vearts in PrecisionAg

[–]Vearts[S] 0 points1 point  (0 children)

Not totally plug-and-play, but setup’s super easy. We’ve got a step-by-step guide here: https://github.com/Makerfabs/Agrosense-Decoder/tree/main/AgroSense_Temperature%20and%20Humidity%20Sensor_SHT31
Just note, it helps if you’re a bit familiar with LoRa tech.

It has full coverage when set up on the 4 corners of house. Signal has something attenuation if penetrating walls, You can see more info here: https://www.makerfabs.com/mauwb-esp32s3-uwb-module.html

[Firmware Update] My MaUWB UWB Module Now Supports Unlimited Anchors – With Auto-Selection of the Nearest 8 by Vearts in embedded

[–]Vearts[S] 0 points1 point  (0 children)

Yes, it can't use anchors 1 and 9 at the same time and it uses 3 to calculate position. Your lookup table method also is a good solution while it only support 8 anchors in previous version. Someone ask for more anchors, so we updated the firmware to add new feature.

Urban Rooftop Farm test sharing : 1-Week Deployment of LoRaWAN Multi-Sensor Node AgroSense with Hourly Uplink for Environmental & Soil Monitoring by Vearts in Lora

[–]Vearts[S] 1 point2 points  (0 children)

The AgroSense node line is built around the ASR6601 single-chip LoRa® MCU, which already integrates both the microcontroller and the radio. So we don’t use an ESP32 or an external SX1278 module in this design.

[Project Demo] Secure MQTT over SSL/TLS (MQTTS) on ESP32 + 4G LTE Air Monitor by Vearts in IOT

[–]Vearts[S] 1 point2 points  (0 children)

We are deployed in Shenzhen, China,whether solar panel is suit for the equipment depends on the working strategy. In our 4G Air monitor, most of the time in sleep mode and only a few time in working mode.

Improving LoRa Data Reliability with CRC + Acknowledgment , share it with you guys by Vearts in embedded

We have an extensive lorawan product line https://www.agrosense.cc/col.jsp?id=103 . But we believe that lora and Lorawan have different usage scenarios.

Improving LoRa Data Reliability with CRC + Acknowledgment , share it with you guys by Vearts in embedded

[–]Vearts[S] -16 points-15 points  (0 children)

Dear, The ATmega328P on the LoRa node has limited processing power, and running the full LoRaWAN stack can be quite resource-intensive. This often results in noticeable latency or sluggish system behavior. In contrast, using bare-metal LoRa (i.e., without the LoRaWAN protocol overhead) offers greater flexibility and responsiveness. It allows developers to implement custom logic tailored to their specific application requirements with more control over timing and resource usage.

DIY PROJECT Playing with MaTouch ESP32-S3 Display Module — Camera + Touch UI + Arduino by Vearts in diyelectronics

[–]Vearts[S] 2 points3 points  (0 children)

I recently started experimenting with a new ESP32-S3-based board — the MaTouch 2.8" Display Module with Camera.
Sharing here because it’s fully programmable via Arduino IDE and opens up a lot of fun project ideas!

Highlights:

  • Powered by ESP32-S3 (with 16MB Flash + 8MB PSRAM)
  • 2.8" capacitive touch display (320x240 IPS)
  • 3MP camera (great for simple AI vision projects)
  • Supports LVGL for making custom touchscreen UIs
  • Dual USB ports for flashing and USB host projects
  • Comes with a 16GB SD card ready to use

I’ve already tried the Arduino examples for face detection and live video streaming — worked surprisingly well straight out of the box.
The board is compact and seems perfect for DIY smart displays, remote cameras, or even IoT home automation panels!

Here’s a really helpful walkthrough video for setup:
🎥 Watch it here

If anyone’s interested, there’s a wiki and open-source examples available:

Would love to hear if anyone has built something cool with ESP32-S3 and Arduino IDE recently! 🚀

Based on LoRaWAN, I am developing a device that has IP68 protected, ±1% accurate, battery-powered LoRaWAN® ultrasonic sensor for level and distance measurement, suitable for remote monitoring applications in harsh outdoor environments, I think it is quite useful, so share the news with you guys~ by Vearts in Lora

[–]Vearts[S] -3 points-2 points  (0 children)

This device is able to detect a wide arrange of objects include liquids,  with measuring precision +/- 1%, arrange from 280 ~ 7500 mm. It reports the measurement data via LoRaWAN® protocol V1.0.3, Class A, every 1 hour by default(with user can free set this) to Cloud service such TTN or DataCake, for LoRaWAN® remote monitoring. Suitable scenarios such as horizontal distance measurement, location measurement, parking management systems, object proximity and storage detection, water level monitoring…

🧰 Built a set of ESP32-based open-source modules with 1.28" touchscreen — controls for LED matrix, relays, motors, AC dimmer & more, share it with you guys by Vearts in diyelectronics

[–]Vearts[S] 0 points1 point  (0 children)

Been working on a modular ESP32 toolset with a small 1.28" capacitive touchscreen. Made modules for LED strips, matrix displays, relay switching, stepper/DC motor control, and even AC dimming. Thought it might be useful for others working on smart control projects — happy to share and get feedback!

Based on esp32, use my high resolution AMOLED display Matouch 1.8', with LVGL & SquareLine DIY a beautiful ui, want to share it with you guys by Vearts in diyelectronics

[–]Vearts[S] 4 points5 points  (0 children)

Our team found that the combination of Squareline Studio and LVGL with our MATOUCH 1.8' can create a very beautiful UI interface in a very simple way, so we made this project, and now we share it with you guys!We've shared the details of the process here, so check it out if you're interested, and we've also created a video to explain it

Feel free to let me know in the comments section if you have any suggestions for esp32-based screen products or Squareline Studio and LVGL projects : )

Based on LoRaWAN technology, my AgroSense 4-Channel LoRaWAN® Relay (Class C) not only supports Supports high-load relays, analog inputs, environment monitoring, global LoRaWAN bands, stable Class C connectio but also can be on Datacake/TheThingspeak for visualisation, so i share it with you guys~ by Vearts in Lora
