ZT-node
ZT-node is a is a wireless sensor network node, a complete modular solution able to integrate several sensors over a single board.
Using Zigbee transceiver we can implement up to 240 different sensors over the same board allowing the realization of different scenarios using the same node. Thanks to the limited Zigbee energy consumption our sensors could live for months without battery change.
Due to its modularity we can adapt the ZT-node to particular situations able to monitor different situations and to satisfy the customer needs.
All the communication aspects are managed by a Zigbee transceiver working in API mode. The node is composed by a PIC microcontroller connected with several sensors:
- Accelerometer
- Light
- Temperature
- Pressure & Moisture
ZT-node was developed during Hydra EU project. Actually it is already available for:
Agriculture Scenario
This scenario is centred about the transport conditions monitoring of pigs. The system is organised like showed in the picture: there is a sink node, in the track, collecting all information coming from each pig. When we reach the desired destination we can download the information storage in the sink node over a local device like a PDA.
ZT-Node Sensors
- Temperature & Humidity sensor
- Noise detector
- Pollution detector(CO and CO2)
E-Health Scenario
ZT-node, equipped with an accelerometer, is used like a fall detector. All the environment is monitored by a central node (sink node) able to connect the fall detector with Internet; when an user, like an elderly person, falls down the system will detect if it is a voluntary movement or an accidentally fall.
We are working to enlarge the scenarios of interest also to building automation and energy saving.
