Lora Soil Moisture Sensor V2

Lora Soil Moisture Sensor V2

Lora Temperature/ Humidity/ Soil Moisture Sensor V2

This Lora Soil Moisture Sensor V2 is a new version of V1, we added the white 3D printed enclosure, and add 2 screw holes on the PCBA board.

Note that the case is not water-proof, as there an AHT10 on the board for air temperature& humidity monitoring, which needs fully contacting with the air.

If you want this module fully waterproof at the cost of a none-air-monitoring, you can make take some glues to stick the few holes on the case. You can also modify& print the case based on our case design.

The Lora soil moisture sensor is based on Atmel's Atmega328P, it collects local air temperature/ humidity with sensor AHT10, and detect the soil humidity with capacitor-humility measurement solution with 555, and transmit the local environment data to the gateway, with Lora communication, suit for applications for smart-farm, irrigation, agriculture, etc.
In applications, always you do not need to check the air/soil state continuously, have a test of them for few seconds after then minutes/hours sleeping is normally Ok for most projects. To save power, there the Air/ Soil measuring functional could be shut down in the working, so they can be only powered ON a short time and then a long time power off. With MCU in sleeping mode and low power consumption Lora module, this module works ok with 2 AAA battery for months. Besides, this sensor is coated with waterproof paint, which makes it a longer working time in damp soil.

Lora Temperature/ Humidity/ Soil Moisture Sensor is shipped out with Arduino pro-mini bootloader pre-loaded, and there's also a default sketch programmed. Uses can re-program it with Arduino IDE, we suggest a standard USB2UART convertor for this. Note that the DTR in the USB2UART convertor is needed to connect to the “Reset” pin for Arduino sketch downloading, if there no DTR, you may need to press the "reset" button manually in the downloading.
