Abstract
En 中文
We show the realization of a simple, small footprint, low power system for wireless transmission of data from a photodiode to an oscilloscope or optionally to a computer. It consists of easily accessible standard modules and electronic parts. Optimization of the setup allowed us to build it around very popular 8-bit microcontrollers and with a minimum number of additional components. The system is particularly suitable for real time, continuous monitoring of spectroscopic signals, light power measurements, optical setup adjustments, and optimization. The average current consumption of the battery powered photodiode and transmitter is as low as 5.2 mA. The system is completed with an optional software oscilloscope, allowing one to visualize the photodiode signal on a computer.
