This ZigBee chip (esp32-h2) does not include wifi. It's probably possible using the esp32-h2 and an esp32, but it's not a good solution. Ah ok thx. The Sonoff bridge apparently works well and it only runs about $12. Other good USB bridges run like $35-60, which is just the price of a few sensors.The ESP32 is constantly monitoring 4 soil sensors. When the soil moisture drops below a user-defined setting, the controller opens that zone's valve and waters the zone for a user-set amount of time. After that it goes into a "soak" mode where it doesn't measure the soil or water it for 10 minutes to give the soil time to absorb all the water.For that price just get an adafruit feather esp32-s3. Much better than the official Dev board. The ESP32-S3 is a great chip, it has several useful features on top of the base ESP32, like USB Host, BT 5.0, and more flash space (usually).For primary batteries the max and min voltage of ESP32 must not be exceeded. Alkaline batteries are cheap, but they need a LDO. Most dev boards have LDOs with a high quiescent current (AMS1117 for example has a quiescent current in the mA range), which is unacceptable for most mobile uses on battery.The ESP32 is constantly monitoring 4 soil sensors.

Yeah I had RGB LED strips running off one USB port, and then the ESP32 running off a separate USB port on the same battery pack. I’m just a hobbyist and it was the simplest solution for me. If I was going to make a more exotic project I would use actual 18650 batteries and a usb battery management module to handle the recharging and prevent ...Not saying the ESP32 is a bad board, it's not a bad board, but these are just prototyping tools. They should be used for "proof of concept" and MVP (Min Viable Product) so that you have a full working model. The commercial product (or close to it) shouldn't have either an Arduino or ESP32. Look at the costs of some of the sub boards you can get.

ESP32 is getting BLE 5.0, despite the earlier 4.2 support it has typically come with. So maybe there's a chance for LE Audio from 5.2, I imagine it would be a rather desirable feature, along with multi-streams. Higher data rate and longer range isn't supported as that needs a hardware update.The RP2040 is the Raspberry Pi Pico is an ARM Cortex -M0+ Dual-core CPU, while the Tensilica Xtensa LX6 in the ESP32 is a 32-bit dual-core CPU , Though an option to get a Single-core variant of ESP 32 is also available. The Pico's CPU runs at 133 MHz, while the ESP32 runs at 240 MHz. As a result, the Arm Cortex -M0+ CPU is significantly slower ...I would suggest MQTT. Use your PC as the broker and spit the data into a sqlite database, or one of your choice. My fridge was on the blink and did this very thing with two esp32s. One went into the fridge and the other had an OLED display, a portable monitor. I also had MQTT running on my pc with the sqlite database.Esp32 Esp32-S2 Esp32-S3 Esp32-C3 Esp8266 Raspberry pi Pico w So I would pick either the S2 or c3 if you need Bluetooth. But be aware of specific configuration to get the Arduino framework working. When starting out with esphome I would recommend an esp8266. D1 mini is the easiest in my opinion.Hi, I'm about to buy my first ESP development board and I don't know which microcontroller version to choose.

ESP32 has been supported in the Matter SDK since the very beginning, and it is currently the only option which can offer both Wi-Fi and Bluetooth LE connectivity. Furthermore, ESP32 supports commissioning (for the initial …

ESP32-S3 Tools: NOT HAPPY. This chip isn't worth developing against. No Arduino support. No PlatformIO nor ESP-IDF Extension support ( idf.py requires "--preview" to target S3 and the extension doesn't know how to do that AFAIK) Even then, the extension doesn't seem to want to build anything.Features: Can connect to thousands of Internet radio stations that broadcast MP3 or Ogg audio streams. Can connect to a standalone mp3 file on a server. Support for .m3u playlists. Can play mp3 tracks from SD card or USB stick (CH376). Uses a minimal number of components; no Arduino required.wake the ESP32 based on accelerometer data. Some accelerometer/gyro/IMU parts support low-power sleep modes with triggerable conditions. These parts will often have an interrupt or event 'pin' which changes state. It's then just a matter of connecting to the ESP32's ext0 or ext1 and configuring wakeup behaviour. 2.

It covers a lot of the best practices (logic level shifting, capacitors for smoothing transients coming from the power supply, resistors at data output pins for stability, etc.).An RFID attendance tracker for (medical) conferences. This replaces the sign-in sheets which makes it possible to credit the attendees their participation points without needing to touch stuff post-COVID. It's an ESP32 + TFT + RFID + RTC, which communicates with an API. The RFID cards are part of the name badges. 2. Easy threading on the ESP32. It's really difficult to chase down race conditions, even with a debugger. Because of that, you may hesitate to use the secondary core on applicable ESP32s. I've created a PlatformIO library to make it almost foolproof to write code that targets the secondary core or just a secondary thread on the primary core.2.

ESP32 is more of a curiosity, and few employers will expect you to know it. So, in my opinion, don't stop studying STM32. It's valuable if you're looking for a job. But, keep working on ESP32, as well. I say this because it's important to know some form of RTOS, and ESP32 basically forces you to use RTOS to make anything work right.At any rate, if you're not looking after long standby times, an ESP32 will do just fine. Of the two, I suspect the esp32 is a better choice. It’s going to be especially useful if you want a wireless device. Pico is definitely an option if you’re okay with only having wired USB as a built-in connectivity option. Nordic semiconductors produce chips that are comparable with esp32 in performance. Look at Microbit as an excellent example of a final product. But you already invested years of engineering time into a Linux based architecture. Esp32 and the like have a completely different architecture, so the transition could turn out expensive.Depending on what you’re looking to build - esphome is a fantastic framework/tool chain to do some pretty cool things really quickly. It starts really simple, but is actually really powerful. 5. Codeeveryday123 • 2 yr. ago. Ok, well, I want to use 4 esp32C3 to have a “monitor” type of feedback.
