The AS3935 is a programmable fully integrated Lightning Sensor IC that detects the presence and approach of potentially hazardous lightning activity in the vicinity and provides an estimation on the distance to the head of the storm. The embedded lightning algorithm checks the incoming signal pattern to reject the potential man-made disturbers. The AS3935 can also provide information on the noise level and inform the external unit (e.g. microcontroller) in case of high noise conditions, with the noise floor generator and noise floor evaluation blocks. The AS3935 can be programmed via a 4-wire standard SPI or an I²C. Also, in case the latter is chosen, it is possible to choose among four different addresses. Two clocks are internally generated by two different RC-Oscillators: TRCO and SRCO. An automatic procedure can increase the precision of those oscillators. The AS3935 can be either supplied by an internal voltage regulator or directly by VDD.
“This project describes the development of a multi-mode scanner platform, which can be described as a Scientific Tricorder. A few years ago, after taking my first contacts with embedded electronics, I decided it would be time to try building a …
“Is a storm on its way? Let’s find out using a circuit based on a sensor to detect electrical shock in the atmosphere capable of letting us know how near and how strong it is. Meteorological centers can monitor …
