Control in the production of oyster mushroom houses by humans still has limitations to monitor temperature, humidity and light intensity. As a result, an innovation is needed, namely by making a prototype oyster mushroom house automatically. This research tool is designed using a DHT22 sensor to monitor temperature and humidity while the LDR sensor functions to monitor light intensity in a prototype oyster mushroom house. The monitoring process on this prototype uses 2 tools, the first as a sender and the second as a receiver. The main materials used to make this research tool are Nano V3 ATMega 328P, LoRa module, DHT22 Sensor, LDR Sensor, and 915 Mhz Antenna. This prototype is more efficient and environmentally friendly because it utilizes LoRa technology which does not require a lot of cables and only uses an antenna as an intermediary. The tool is able to maintain the temperature and humidity of the mushroom house when the monitoring results in the prototype will be well monitored and under normal conditions in the oyster mushroom house with temperatures below 29℃, humidity below 80%, and light intensity below 60%. If the temperature and humidity exceed normal limits, a relay in the form of a fan will automatically turn on to cool the room in the oyster mushroom house.
