$12 Plant Bot is an ESP32-C3 soil sensor and pump driver for fully automated indoor plant care

The Plant Bot is an open-source, Internet-enabled plant monitor powered by the ESP32-C3 microcontroller and integrating a corrosion-resistant capacitive moisture soil sensor and a pump driver on a single printed circuit board, eliminating the need for additional cabling. The Plant Bot is designed to automate indoor plant care by combining moisture sensing, light sensing, and pump activation. It can be powered via USB or a single coin cell battery which lasts up to a week with daily updates. An onboard multi-color LED visually represents the current soil condition, ranging from red (dry) to blue (moist). The “Soil Level” line on the board indicates the maximum depth to which the sensor or device should be inserted into the soil. According to the maker, the Plant Bot will remain unaffected by corrosion if the soil level does not exceed this line. Other solutions we’ve covered with a soil sensor usually separate the […]

LoRaWAN no code ESP32-S3 development platform offers Arduino MKR, MikroBus, FeatherWing, and Grove expansion (Crowdfunding)

Sheffield-based IoT company, inx-systems has developed a programmable LoRaWAN IoT module and a development breakout board that integrates with Arduino MKR, Adafruit FeatherWing, Grove, and mikroBUS shields. The module is powered by an ESP32-S3 microcontroller which comes preloaded with inx’s no-code LoRaWAN software development platform, Lucid. The WAN-4-ALL module has built-in Wi-Fi, Bluetooth, and LoRaWAN connectivity via the ESP32-S3 microcontroller and Seeed Studio Wio-E5 module. This makes the module suitable for short-range, medium-range, and long-range IoT applications such as remote monitoring, home automation, industrial control, and smart agriculture. We have covered other LoRaWAN development platforms such as SB Component’s RAKWireless-based products, Particle’s multi-radio devices, and the UnPhone. The WAN-4-ALL module differentiates itself with the preloaded no-code LoRaWAN development environment and multiple connectivity options. WAN-4-ALL module specifications: SoC – Espressif Systems ESP32-S3 dual-core microcontroller @ 240MHz with Wi-Fi 4, Bluetooth LE 5 LoRaWAN Module – Seeed Studio Wio-E5 Module based on […]

XIAO Powerbread power meter for breadboard

BredOS Arch Linux Arm distribution runs on Rockchip RK3588 single board computers

BredOS is a Linux distribution based on Arch Linux Arm and optimized to run on Rockchip RK3588/RK3588S single board computers (SBCs) with current support for 22 boards from Radxa, Orange Pi, Khadas, and others. Board vendors will usually provide OS images for their SBCs, but the quality and support may be limited, so projects like Armbian and DietPi are maintaining Ubuntu and/or Debian images for popular single board computers. But if you’re an Arch Linux (Arm) fan, there are fewer choices, and you may have to roll your own port for your board. BredOS provides an easy-to-use alternative based on Arch Arm Linux. BredOS highlights (provided by the developers): User-Friendly Interface – A simplified and intuitive user interface for easy navigation and use. Arch-Based – Built on top of Arch Linux, ensuring access to a vast repository of packages and a rolling release model. Arm Support – Optimized for Arm-based […]
