Matter compatible ESP-ZeroCode modules enable plug-and-play automation solutions

Espressif Systems has just announced the Matter-compatible ESP-ZeroCode modules with Wi-Fi and/or Thread (802.15.4) wireless connectivity that are designed as plug-and-play solutions for LED lights, outlets, switches, dimmers, relays, fans, and other lighting and electrical devices. I was only recently introduced to no-code programming in a recent post by Ninephon Kongangkab explaining how to use SenseCraft firmware for no-code programming on Wio Terminal. Basically, there’s no need to know Arduino, MicroPython, or any programming language, as the user just has to press a few buttons to configure an IoT device to meet his/her requirements. With the ESP-ZeroCode modules, Espressif offers something similar using several of their ESP32 chips. The first ESP-ZeroCode modules will be offered with either ESP32-C3 (aka ESP8685) or ESP32-C2 (aka ESP8684) WiFi & BLE RISC-V SoCs, or ESP32-H2 802.15.4 & BLE RISC-V microcontroller, and ships with a Matter compatible firmware that enables “near-zero investment in development”.

Bee Motion ESP32-S2 PIR motion sensor offers GPIOs, over a year of battery life

Smart Bee Designs’ Bee Motion is an ESP32-S2 board with a PIR motion sensor, some GPIOs for expansion, and promising over a year of battery life under the right circumstances. If the name “Bee Motion” rings a bell, it’s because we covered the Bee Motion Mini board last month with an ESP32-C3 processor and a PIR sensor, but no USB port for programming and no expansion ability. It was just designed to be used as a battery-powered wireless PIR motion sensor. The Bee Motion expands the use cases of the solution, although it only features WiFi connectivity, and loses Bluetooth LE. Bee Motion specifications: Wireless module – Espressif ESP32-S2-MINI-1 module with Espressif ESP32-S2FH4 single-core 32-bit LX7 microcontroller @ up to 240 MHz, RISC-V ultra-low-power co-processor, 320 kB SRAM, 128kB ROM, 2.4 GHz WiFi 4 connectivity, 4MB flash, PCB antenna PIR sensor – Passive infrared motion sensor with dome lens, 5-meter […]
