Information on measurement results is sent in various ways to the user. This method of measurement can be done by using radio frequency as a sending device data, in order to obtain data fastly and accurately. Therefore we need a tool that can be used to make measurements remotely. This long distance measurement requires a transmitter. The transmitter used in this tool is a type of ESP32 microcontroller which produces a wifi signal emission. Each component that is designed will be used as a station. The manufacturing of this tool is designed to determine the temperature and humidity values of a place, as well as to know the results of the image from a camera that has been integrated with the ESP32 microcontroller remotely. The results of the study show that the ESP32 microcontroller can transmit temperature data values, humidity data values and image results from the camera properly. This is evidenced from the measurement results of the error value where the value is obtained from the DHT22 comparison sensor with the HTC-1 measuring instrument, so that the outdoor error value for temperature is 1,1% and the error value is 0,58%. While the error value in the room for temperature is 1,05% and the error value is 0,85%} }
