Mapping the Mangroves Wireless Temperature Sensor

Mangroves are very sensitive to changes in temperature over time. We want to measure the air and water temperature around mangrove trees to better understand this correlation.

This tutorial will show you how to assemble the Mapping The Mangroves Wireless Temperature Sensor.

Step 1: Materials Required

This project requires the following:

Solar Panel
Arduino Sensor Shield
2 ENV-TMP Temperature Sensors
Saboten Sensor Node
2.4 GhZ Antenna

Step 2: Install the Arduino Shield

The Arduino Sensor Shield will only work properly if it's installed the right way around. Its pins must align with those of the Saboten board (pictured with red outlines).

Place the Arduino Sensor Shield on top of the Saboten board and make sure the pins are aligned on each side. Then gently push down until the two boards are attached to one another,

Step 3: Installing the Air Temperature Sensor

The ENV-TMP has 3 colored wires (Red, Black, White) on one end, and a silver probe on the other. The probe is what senses the temperature. The wires need to be attached to the blue screw terminals on the Arduino Sensor Shield in the right way.

Looking at the shield, you will see that three of the blue screw terminals are under the heading "TEMP" and have "W B R" written across from them. These letters correspond to the color of the wire that needs to be inserted.

Place one wire into the silver area of each screw terminal and tighten it down gently. You don't want to screw it down so hard that you break the wire, but you do want to make sure that the wire is securely fastened.

This will be our Air temperature sensor.

Step 4: Installing the Water Temperature Sensor

The ENV-TMP has 3 colored wires (Red, Black, White) on one end, and a silver probe on the other. The probe is what senses the temperature. The wires need to be attached to the blue screw terminals on the Arduino Sensor Shield in the right way.

Looking at the shield, you will see that three of the blue screw terminals are under the heading "RGB" and have "R W G" written across from them. These letters correspond to the color of the wire that needs to be inserted.

The "R", or red, terminal is shared with the Air Temperature Sensor from the previous step.

Place one wire into the silver area of each screw terminal and tighten it down gently. You don't want to screw it down so hard that you break the wire, but you do want to make sure that the wire is securely fastened.

This will be our Water temperature sensor.

Step 5:

The Saboten board has a Solar battery charger built-in. There are two connectors along the edge of the board labeled "Solar" and "Battery". These connectors mate with the connectors on the wires from the solar panel and battery. They will only go in one way around, do not try to force them into the connectors.
