Soil moisture monitor using the WSN1101L (Low profile mesh node)

The low profile of our new offering (WSN1101L) allows it to be easily integrated with the Chirp soil moisture sensor. I glued the WSN1101L to the top of the moisture sensor and connected the two with 5 wires (Vcc, ground, I2C-SDA, I2C-SCL and RESET). The moisture sensor “stick” has a coin cell retainer which can hold a 20 mm CR-2032 coin cell. This coin cell powers both the moisture sensor and the WSN1101L. The WSN1101L has a flexible whip antenna connected to a U.FL connector on the radio board.

Here are some pics.
