DIK-G330 IoT Logger, 8ch & Multi-function Soil Moisture Sensor SetNEW!
Main Characteristic
This is a set of 8 sensors (with logger connection) and an IoT logger, 8ch. The logger can be connected up to 8 units of the sensors, and is equipped with a solar panel, so that it is possible to observe for long-term monitoring if there is no electric power in a field. It has a built-in SIM card, which includes five years of fees for the communication and cloud system usage in the purchase, therefore, you can start data communication right after installing at the field without any troublesome operations. Measurement data is automatically updated to DAIKI’s dedicated cloud system, you can view and download the measurement data at any time on your smartphone or PC.

Q&A
Q: When I want to measure moisture, do I need to insert the entire sensor part (pin part) into the soil?
A: Yes, it is necessary to insert the entire sensor part into the soil. If it is inserted only halfway, the measured moisture value will tend to be lower than the actual value.
