CH-S02 digital temperature and humidity sensor

The CH-S02 digital sensor is a device that is used to measure the temperature and relative humidity of the air. 1. PRODUCT APPLICATION 2. MANUFACTURER'S WARRANTY 3. TECHNICAL SPECIFICATIONS 4. SENSOR CONNECTION 5. SENSOR POSITION CH-S02 advantages: Allows simultaneous measurement of ambient temperature and humidity; Allows temperature measurement in the range from -40?C to +85?C; Temperature measurement accuracy ?0.5?C Allows you to measure the relative humidity in the range from 0 to 100%; Relative humidity measurement accuracy ?5%; The small dimensions of the device - 5.25mm * 12mm * 15.2mm The case is protected by IP-40 technology, which allows you to protect the structure from dust on live parts. 1. Product Application CH-S02 is a combined digital sensor, which can simultaneously measure the temperature and relative humidity of the ambient air. The CH-S02 sensor can be used to measure the environment both indoors and outdoors. 2. Manufacturer's warranty Warranty period - 1 year from the date of sale. Products that were transported, stored, installed and operated in violation of the requirements for these products, as well as having mechanical damage, are not subject to warranty replacement. Do not use the device in any way other than those specified in this manual. The manufacturer does not bear warranty obligations in case of non-compliance with the rules of operation, changes in the design or painting of the device. Immediately after opening the package, be sure to check the device for damage. If there is visible damage, do not connect or use the device. 3. Specifications Nominal supply voltage* 3.3 V Measuring range  -40?C to +85?C Temperature measurement accuracy in the range -10?C to +85?C ?0.5?C Temperature measurement accuracy in the range -55?C to -10?C and +85 ?C to +90?C ?2 ?C Measuring range  relative air humidity 0-100% Relative air humidity measurement accuracy ?5% Maximum wire length (in case of extending the wire supplied with the sensor) 50 m Data transfer interface (data bus) S-Bus Degree of protection IP-40 Power supply is provided by the ConnectHome device to which the sensor is connected. 4. Sensor connection Temperature and relative humidity sensor, connected to a special S-Bus connector, located on some ConnectHome devices. In the Z-Wave network, the sensor is displayed as a structural unit (endpoint) of the module to which it is connected. Data is transmitted to the control controller using Z-Wave radio commands. If it becomes necessary to connect the sensor after connecting the module to the Z-Wave network, you must first remove it, and re-add it after connecting the sensor. 5. Placement of the sensor To measure the temperature and humidity of the air in the room, the sensor is installed at a height of approximately 1.5 m from the floor level and at least 0.5 m from the corner of the room. The sensor should not be installed on external walls or other objects that may distort the temperature sensor data. Avoid places where the sensor can be exposed to direct sunlight or drafts, as well as splashing water and other liquids. The effect of significant heat generation on the sensor should be excluded. Please note that ConnectHome modules generate little heat, placing the sensor close to the module (less than 20 cm away) may distort temperature data. To measure humidity and temperature outdoors, position the sensor in a location that avoids direct exposure to moisture and sunlight.
