Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Forest fires are a great threat to ecologically healthy grown forests and the protection of the environment. The root cause is due to the lack of a scalable network to monitor the physical conditions over vast forest areas. To overcome this, we used the NRF24L01+ module configured in mesh network mode interfaced with Arduino along with DHT22, MQ2 sensors, powered by Lithium-ion batteries which can be recharged with solar panel, this allows the node to reconnect to the network automatically in case of any damage to its parent node.

Arduino, DHT22, MQ2, Mesh Network, NRF24L01+, Raspberry Pi, Wireless Network.
