The OPTIN Sensor Protocol is a lightweight communication protocol for data transmission between Internet of Things (like smart devices, sensor networks).

This is the protocol used by our company's hardware products. It provides numerous optional solutions to guarantee that the critical packets reach their destination and that the number of lost packets are reduced. It's simplicity makes it a perfect choice for devices with scarcer resources. The additional cost per packet is between 2 and 4 bytes. We recommend using it for communication between various data collector devices since the protocol supports frequent data sampling, interactive device maintenance and firmware update.
