  1. Thanks for sharing the project. Here is another good project based on DHT11. This is done with ESP8266. But it can be done with ESP32 too. This is a room-temperature monitor. We can use it to monitor our room from anywhere in the world with dht11: https://www.pcbway.com/project/shareproject/Room_Temperature_Over_Internet_With_BLYNK_ESP8266_DHT11_91b0d3f5.html
  2. A suitable microcontroller for this project would be the ESP32. It's a budget-friendly microcontroller with built-in Wi-Fi capability, which makes it easy to connect to the internet and fetch real-time data. The ESP32 also has plenty of GPIO pins for controlling multiple bells and interfacing with other peripherals. You can also print PCB of your project from PCBway. https://www.pcbway.com/project/shareproject/ESP32_Power_Montiroing_PZEM_004T_and_Relay_Control_c8098cc0.html
  3. Good project. I can see another ESP32 Webserver for Home Weather Station PCB. https://www.pcbway.com/project/share/ESP32_Webserver_for_Home_Weather_Station.html
  4. Very good project. If you want to customize an ESP32-C3 board of yourself, you can see the BOM here: https://www.pcbway.com/project/shareproject/ESP32_C3_DevBoard_208483e1.html
  5. Thanks a lot for the elaborate tutorial. Here I found another Neopixel ring clock. This one is also nice and well built. https://www.pcbway.com/project/shareproject/NeopixelQuarterRing_cbc70e1a.html
  6. Thanks a lot for sharing this project. Earlier, I came across many telegram-related projects like this. https://www.pcbway.com/blog/PCB_Design_Tutorial/ESP32_CAM_with_Telegram__Take_Photos__Control_Outputs__Sensor_Readings_and_Motio.html Your blog is much more elaborate.
  7. You can post your query to digikey forum.
  8. Thanks for the detailed discussion of the project. Here somebody designed a smaller alternative https://www.pcbway.com/project/shareproject/Atiny_85_crypto_miner_9415f34a.html It is based on Attiny85.
  9. I think for this type of smart projects, you must choose STM microcontrollers. With Arduino, the nearest thing I could find is this one: If you just want to make simple Arduino-based school bell, you can follow this design: https://www.pcbway.com/project/shareproject/Arduino_School_Bell_Simple_DIY_058abe6e.html
  10. Yes. The link I posted. The smart grocery cart project.
  11. If you are interested, you can make a PCB of your project: https://www.pcbway.com/project/shareproject/Battery_powered_and_compact_design_ESP32_temperature_and_humidity_sensor_ba934715.html This PCB also features ESP32 and DTH11. It's quite compact.
  12. Can these modules E73-2G4M04S1A, E73-2G4M04S1B, E73-2G4M08S1C, E73-2G4M04S1D be used instead of ESP8266?
