Project Overview2020-2022

Fan Controller PWM TestingThe temperature inside the curing chamber was monitored with a combination of fans, heaters, and refrigeration. The fans were controlled with a PWM signal to achieve an airflow that closely adheres to the desired temperature profile.

PCB Design

A combination of 3D printed components, off-the-shelf plastic enclosures, and a custom CNC milled screen window, the enclosure provided a simple installation and interface for the operator to view the status of the system and control the crane.

Features

The Satellite Logger was equipped with a number of features to provide reliable and secure data transmission over the Iridium network.

Iridium Connectivity

The logger was equipped with an Iridium modem to provide reliable and secure data transmission over the Iridium network.

Automatic Data Logging

The logger was equipped with a microcontroller to automatically log data when the Iridium modem was able to connect to the network.

Heads Up Display

The logger was equipped with a 2.8" LCD screen to provide a heads up display for the operator to view the status of the logger and the temperature readings from the probes.

Custom Data Compression

The logger was equipped with a custom data compression algorithm to minimize the amount of data sent over the Iridium network, reducing costs by more than 80%.

Low Power Consumption

To extend the battery life of the device, a low power SoC was used, along with power routing to prioritize vital functions like the Iridium modem and temperature sensors.

802.11 Radio

The logger is Bluetooth and WiFi enabled to allow for on-the-spot configuration and updates to the device.

Power Alerts

The logger was equipped with a battery status display to provide the operator with the remaining battery capacity of the logger.

Temperature Readings

The logger was equipped with thermistor probes to measure the temperature of the concrete.
