MonkMakes Plant Monitor for micro:bit

SKU: MONK 096
Sale price €14.95

VAT included

Shipping calculated at checkout

The MonkMakes Plant Monitor makes it easy to build a simple “smart plant” project with the BBC micro:bit. It measures soil moisture (using a corrosion-resistant capacitive sensor), plus temperature and relative humidity, so students can log data, set alerts, or create an automatic watering warning system.

Key Features:
  • 3-in-1 monitoring: soil moisture, temperature and relative humidity.
  • Capacitive moisture sensing (no electrical contact with the soil), helping resist corrosion.
  • Simple micro:bit connection via alligator/crocodile clip rings.
  • Human-readable UART serial interface for quick integration with code.
  • Additional analogue output (moisture only) for optional analogue reading.
  • Built-in RGB LED for clear, visual status feedback.


    • Classroom Uses:
  • Plant care investigations: compare watering patterns and environmental conditions.
  • Data logging and graphing activities (STEM / Computer Science / Geography links).
  • Build rule-based alerts (e.g., “too dry”, “too humid”) using the RGB LED.


    • Note: As with any soil probe, keep the electronics section dry and only insert the sensing prongs into the soil.
