EMJ MIJ-12 Waterproof Logger

Installation of soil moisture sensors is often wide-area multi-point observation, so-called scattered observation.
The challenge is how to recover the many sensor outputs. There is also a method of using a data logger that can input multiple points, but there is a limit to the extension of the sensor cable, and the longer it is, the worse the handling will be, and the noise and trouble will increase.
For loggers with high power consumption, it is also necessary to prepare peripheral devices such as solar power generation and batteries. In such a case, if MIJ-12, which has a waterproof capacity equivalent to IP67, is adopted, the logger part can be installed on the ground surface, or everything including the logger can be buried in the ground..

MIJ-12 has a logger, circuit, and power supply built into a waterproof and impact resistant case, so it is compatible with the soil moisture sensor and can be used in various places. When high-precision soil moisture measurement is required, there are various combinations such as ADR type theta probe, SM150T, and when cost is prioritized, such as Meter’s EC-5 and optical sensor MIJ-14 series.

You may not need PR-01, If connecting MIJ-03 or MIJ-14 sensor that do not require power.
