Thousands of dollars of energy can be wasted running industrial fans when plants are empty. Companies need an efficient and “greener” alternative to manage energy costs during shift fluctuations.
DornerWorks designed a system that accurately transmits long term on/off data (up to a year) into a handheld remote and synchronizes the programming from the computer into the handheld device.
In this industrial project, we worked to design the control system hardware for this wireless application. In this case, we designed the complete system, including an infrared communication protocol, PC support software, low-power infrared transmitter, and low-power infrared receiver that allowed communication at about 70 feet. All of this was accomplished within the constraints of a small ~70mA transformer with less 5V (AC) power.
