IPWC: Integrative Peer to Peer Wireless Communication of MEMS based Remote Temperature Sensor using ESP NOW and IoT Networking

One of the most cutting-edge technological advancements of the modern era is wireless communication. Long-range and short-range services are both largely owing to wireless technology. There are numerous wireless communication techniques available today like Bluetooth, WiFi, etc. But one such peer to peer network based protocol is ESP-NOW, which can communicate between two ESP microcontrollers without WiFi connectivity. ESP-NOW is a wireless communication protocol that can transmit data at comparatively quick transfer rates over great distances and is needed for the Internet of Things in order to exchange the necessary data swiftly and in real-time. Present remote temperature sensor uses ESP-NOW for successful trans-reception of the temperature values at low latency and low power consumption. In the experiments conducted, the ESP-NOW gateway successfully receives all the packets of data with a success rate of 100% which is at a distance of up to 20 meters from the transmitter or the initiator.
