Frequently Asked Questions
Q: How does the soil moisture sensor automatic irrigation kit work?
A: The soil moisture sensor probes are inserted into the soil. When the soil dries below a set threshold, the sensor sends a signal to the relay module, which activates the water pump. Once adequate moisture is detected, the pump automatically stops — ensuring your plants get just the right amount of water without waste.

A: Yes! This kit supports 4 individual channels, allowing you to water up to 4 separate plant zones or pots simultaneously. It's ideal for greenhouses, garden beds, or collections of indoor potted plants.
Q: Is this kit easy to assemble for beginners?
A: This is a DIY kit designed for hobbyists and electronics enthusiasts. Basic familiarity with simple wiring and electronics is helpful, but the components are straightforward to connect. It's a great hands-on project for those interested in smart gardening or Arduino-style electronics.
Q: What power supply does this automatic watering system require?
A: The kit is compatible with standard low-voltage DC power supplies commonly used in DIY electronics projects (e.g. 5V or 12V depending on your pump). Please refer to your pump and module specifications to match the correct power input for your setup.
