An ambient light sensing module for wireless sensor networks for planetary exploration

► Wide range light sensing module for Planetary Wireless Sensor Networks is designed. ► Performance of the module is evaluated for ambient illuminations <1 lx-120 klx. ► Variations measured in sun and moon light intensities demonstrate its sensitivity. ► Illumination of planet surface can be inferred by sensor network using these modules. ► Prospective tool for future planetary exploration tasks.
