Some of the key product highlights for the new AS3935 include: Detection range up to 40 km which is far beyond human senses. Capability to detect BOTH cloud to ground and cloud to cloud. Operation in battery operated applications that need 2.4 to 5 V operation and low power modes with a listening mode current draw of only 60 mA. A sophisticated algorithm that helps to minimize false disturbers and to give distance estimation up to 40 km. Integrated automatic antenna tuning that ensure the antenna is always centered for optimal performance. Choice of interfaces of either an I2C or SPI in a very small and compact 4 x 4 mm MLPQ-16 package. With the release of the AS3935, ams OSRAM is introducing a new category to the portable sensor market that was non-existent before.
