Q&A

What sensors are compatible with the X2 data logger?
Bridge telemetry unifies two types of wireless communication methods into a single X2 data logger. Most commonly, it can be used establish a network of radio data loggers that link to a single radio-to-cellular repeater. That way, one cellular data plan is used to transmit data from the entire network, resulting in lower recurring data costs.
