Overview

The sensors this tutorial covers are:

- Vaisala CO2 sensor

- CO2meter CO2 sensor

- Dracal Temperature and Humidity sensor (TRH300)

Please refer to the appropriate sections below for the device or combination of devices you have purchased.

Before you begin: 

For each unit you are going to install, make sure there is a power outlet or power strip nearby (within 6 feet or so). If not, use a power strip or extension cord to bring power over to your incubator. Be careful to place any power strips or extension cords such that they will not be tripped over, accidentally unplugged or turned off.

Make sure you have any necessary PPE (e.g. gloves, safety glasses, lab coat).

Also make sure that the area of the incubator near the sensor port is clear (i.e. no samples in the way).

Getting started: 

Unpack your links, sensors, WiFi antennas, and power supplies. You will also have optional mounting kits and microUSB cables (for WiFi setup) for each link.


All of your sensors cables will run out the sensor port to the link. Some of these cables are quite thick, so please be aware that some installations will be more difficult than others depending on the type of stopper used in the port and if there is anything already installed.

Vaisala

The Vaisala sensor will be mounted on the side of the incubator with a cable clip and ziptie as shown below. The first step is to prepare this mount, as this is easier to do outside of an incubator.

1. Loosely ziptie the cable clip to the sensor first and then slide it off.

The Vaisala CO2 sensor fits through the sensor port on most incubators.

2. Remove the stopper and pass the sensor body through the port so that it rests on the first shelf in the incubator.

3. Then peel the backing off of the cable clip and ziptie that you prepared.

4. Install this clip on the side of the incubator, about halfway towards the back. The middle of the sensor will be at this point, so be careful that it is not too far forward. The sensor should be mounted horizontally, so the ziptie loop should be oriented correspondingly.

5.Slide the sensor body through the loop and tighten.

6. Trim the end of the ziptie if desired.

At this point your sensor is installed, and the USB connector is hanging from the incubator. Proceed either to Dracal TRH300 or Link installation.

CO2meter

The CO2meter CO2 sensor is mounted with 3M Dual Lock mounting tape on the sidewall of the incubator. This sensor does not generally fit through the sensor port on an incubator, so installation is done from the front of the instrument and the USB cable is then passed through the sensor port.

  1. Remove the backing on the mounting tape

2. Place the sensor on the wall of the incubator midway to the back or further, on the same side as the sensor port (or wherever is easiest for cable routing).

3. Then pass the USB cable out the sensor port so you can plug it into the link.

At this point your sensor is installed, and the USB connector is hanging from the incubator. Proceed either to Dracal TRH300 or Link installation.

Dracal TRH300

The Dracal TRH300 temperature and humidity sensor can easily fit through an incubator sensor port. It must be installed facing downward, to avoid buildup of condensation (as reccommended by the manufacturer.)

1. Pass the sensor through the port, giving it enough slack that you can mount it pointing downward.  

2. The first inch or so (the non-flexible part) of the probe tip is the circuit board - this is the part that must be installed pointing down. Use a cable clip to secure this part of the sensor to the wall of the incubator.

At this point your sensor is installed, and the USB connector is hanging from the incubator. Proceed to link installation.

Link Installation

1. First, screw on the WiFi antenna.

2. If the side of the incubator is magnetic, you can simply place the link where you want it and the internal magnets will hold it securely in place.

You also have the option to use the Dual Lock mounting tape (left) or the wall-mount hardware (right).

3. Plug in the power cable.

4. Plug in the sensor cable(s). They should easily reach around from the sensor port behind the incubator. Follow included instructions for which USB port to use.

5. Bundle up the loose wires as much as you can and attach them to the side of the incubator with cable clips. This will reduce the risk of things getting unplugged by accident.

You're all done with physical installation! Now you can proceed to WiFi setup or dashboard setup.

Tips:

After plugging everything in, make sure the green light on the Link is on.
