Solar Powered Wireless Equipment for Multi-Purpose Disaster Risk Reduction
Questions for Mr. Ruel Lopez of MVERT (Morong Volunteer Emergency Response Team):
1. How to make our project waterproof?
Answer: Put the project on a High place or secure it with a glass case
2. What are we going to do to improve our project?
