CJMCU-3935 AS3935 Flash Sensor Strike Detection Storm Distance Module

Description The AS3935 is a programmable fully integrated flash sensor IC that detects the presence and approach of potentially hazardous flash activity in the vicinity and provides an estimation on the distance to the head of the storm The embedded flash 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 IIC 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 Feature Flash sensor warns of flash storm activity within a radius of 40kmDistance estimation to the head of the storm down to 1km in 14stepsDetects both cloud to ground and intra cloud cloud to cloud flashesEmbedded man made disturber rejection algorithmProgrammable detection levels enable threshold setting for optional controlsSPI and IIC interface is used for control and register readingAntenna turning to compensate variations of the external componentsSupply voltage range 2 4 5 5VPower down listening and active modePackage 16L
