Cirronet Inc. introduced enhanced I/O capabilities for its LPR2400/ER family of cost-optimized, low-power 802.15.4 modules. The LPR2400/ER provides sensor data collection for different applications that monitor operating conditions of equipment and facilities such as temperature, humidity, lighting, moisture, vibration and barometric pressure.

LPR2400/ER features analog and digital I/Os. Its point-to-point, point-to-multipoint and router-relay capabilities provide connections with up to 1,000 nodes without the complexity of mesh networking.

The LPR2400/ER's firmware is designed to improve OEMs' time-to-market. It enables user access to the I/O over the serial port and remote module capabilities that automatically report readings based on user-settable timers and interrupts. Using the device, users can also set threshold levels that send messages to the base station alerting of the exception condition.

Moreover, LPR2400/ER can be set to enter sleep mode and be programmed to wake up at a specific interval or based on an interrupt generated by an external event or condition. While awake, the LPR2400/ER can be set to send one of three user-selectable messages and then return to sleep immediately or to remain awake for a specified period of time to receive application messages. This eliminates the need for polling, and saves battery power and RF bandwidth.
