XIAO Soil Moisture Sensor review with Home Assistant

Seeed Studio sent us a review sample of the XIAO Soil Moisture Sensor powered by the XIAO ESP32C6 wireless module and running on a single AA battery. Designed for ultra-low power consumption, it’s supposed to offer long-lasting operation with dynamic adjustment of monitoring intervals. It’s preloaded with ESPHome firmware and is fully compatible with Home Assistant. It’s ideal for indoor plants monitoring, but it can’t be used outdoors since the 3D printed enclosure is not weatherproof. In this review, we’ll start with an unboxing, do a quick teardown, and test it with Home Assistant to receive a notification on our smartphone when the soil is dry. XIAO Soil Moisture Sensor specifications Wireless module – XIAO ESP32C6 Wireless MCU – Espressif Systems ESP32-C6 CPU 32-bit RISC-V core up to 160 MHz Low-power RISC-V core up to 20 MHz Memory – 512 KB SRAM, 16KB low-power SRAM Storage – 320 KB ROM, 4MB […]
