1-Wire temperature, humidity and brightness living room sensor, surface mounting, unassembled board Unassembled board for the construction of a living room sensor for temperature, humidity and brightness. The circuit boards are industrially manufactured, plated through and provided with solder resist. The product photo of the assembled PCB shows only an example of a completely assembled board. Printed circuit board for Multisensor / living space sensor for accurate temperature and humidity measurement. A DS18B20 sensor is used for temperature measurement, and a high-precision Honeywell sensor is provided for humidity measurement. The light sensor has a measuring behaviour similar to the human eye and therefore reacts specifically to visible light and not to UV light as with many sensors. The light sensor is suitable for detecting sunrise/set. Scope of delivery: Unassembled board in industrial quality without components or housing. Building instructions per downloadNote: SMD components must be assembled on the board. 1-Wire components DS18B20, temperatureDS2438 Multisensor for air humidity Temperature sensor DS18B20 Accuracy 0.5° in the range of -10°C - 85°C Resolution 9-12 bits, 0.5°C-0.0625°C/bit, depending on the selected resolution Air humidity sensor Capacitive sensor (Honeywell HIH4000 series) Accuracy 3-8% in the range of 5-95% relative humidity (non-condensing) Repeatability 0,5% brightness sensor Sensor adapted to the sensitivity of the human eye Measuring range 2 - 7000 lux Resolution 9 bit, approx. 0.32% humidity 1-Wire connection 3 - conductor connection (data, ground and 5V, parasitic operation not supported) Operating voltage 5 V= (+/-10%) Power consumption max.2mA Connection: RJ45 modular socket and Push In terminal Dimensions Printed circuit board: 67 x 67mm (LxWxH)Installed in sensor housing: 71 x 71 x 32mm (LxWxH)
