A wireless intelligent image sensor node was designed. The hardware processing platform combined chip CC2430 and LPC1766. Image frame, which was collected by the serial camera, was divided into many packets which were transmitted through ZigBee protocol one by one. The experiment results showed that the node’s maximum communication distance was 160m, and the node packet loss rate was low. In addition, the JPEG format image acquired by camera was about 10kB which takes 135s to transmit via ZigBee. The designed node, with compact structure, stability work condition and low power consumption, could realize acquisition and transmission of the greenhouse environment information. So, it can meet the need of the greenhouse environment monitoring.
