[Debasish Dutta] has made a number of weather conditions stations in the previous, and this, the fourth version of the system has experienced many of the feature requests from earlier customers rolled in. The station is intended to be employed with an external climate sensor unit, delivered by Sparkfun. This handles wind speed and way, as effectively as measuring rainfall. A customized PCB hosts an ESP32-WROOM module and an Ai-Thinker Ra-02 LoRa module for management and connectivity respectively. A PMS5003 sits on the PCB to measure those people particulate densities, but most sensors are connected with basic 4-way I2C connectors. Temperature, humidity, and strain are taken care of by a BME280 module, UV Index (SI1145), obvious mild (BH1750) even soil humidity and temperature with a cable-mounted SHT10 module.
All this is powered by a solar panel, which charges a 18650 cell, and keeps the display managing during the darker hrs. For debugging and deployment, a USB-C ability port can also be applied to supply charge. A 3D printed Stevenson display sort enclosure enables the air to flow into amongst the PCB-mounted sensor modules, without hopefully also a great deal moisture building it in there to induce mischief.
On the data collection and visualization side, a companion LoRa receiver module is in development, which is meant to move alongside measurements to a wide range of expert services. Believe Property Assistant, ESP house, and that variety of issue. Program is still a work in development, so perhaps examine back afterwards to see how [Debasish] is finding on with that?
This sort of multi-sensor hosting challenge is almost nothing new listed here, here’s a 2019 Hackaday prize entry along the similar strains. Of course, collecting and logging measurement facts is only aspect of the difficulty, visualization of people measurements is also essential. Why not use a mechanical strategy, such as a diorama?
