Snitch is an intelligent and flexible transmitter designed to interface data traffic between sensors and the final application of an IoT solution. It aims to enable IoT solutions in several segments with features such as internal rechargeable battery, positioning, motion detection, digital inputs for sensors and serial for connecting peripherals. Among its resources, Snitch also includes 4G / 2G (LTE) and LoRa technologies.
