Temperature sensor T811, 2m
Temperature sensor for measuring an ambient air temperature indoors from -40°C to +125°C. Avoid water contacting a temperature sensor!
Temperature sensors (T811) are designed for measuring an air temperature indoors with no possibility for water to get at the body of the sensor. Sensors are made in the form of the board, installed at the plastic body with slots.
Temperature sensors are connected to NetPing 2/PWR-220 v2/SMS, NetPing 2/PWR-220 v1/SMS, NetPing 2/PWR-220 v3/ETH devices. The information about connecting temperature sensors (T811) is given in the documents «User guide» for corresponding NetPing devices, to which they are connected. The information about configuring temperature sensors (T811) is given in the documents «Firmware description» for corresponding NetPing devices, to which they are connected.
All temperature sensors are connected in parallel to each other, to the same contacts. A body of each temperature sensor has a model of a sensor indicated. Before using a temperature sensor, there is a need to set an address of a temperature sensor independently. An address of a temperature sensor is set by extracting a board of a temperature sensor from a body and by setting mechanic switches (jumpers) into certain location using a screwdriver, included into a shipping kit of a NetPing device, or manually:
There must be no temperature sensors with similar addresses for a NetPing device among connected temperature sensors!
It is possible to plug up to eight temperature sensors (T811) with loops of maximum length up to 10 meters for each sensor individually to each NetPing device. A topology «star» is used with a device in the centre and 10-meter «rays» to temperature sensors.
A loop of a temperature sensor is 4 wires, which transmit the information about a temperature in a digital form. A loop is inseparably connected to a sensor and is 2 meters long. If necessary, it is possible to extend a loop of a temperature sensor using RC sensor loop extenders, 4m plugged into each other.
A sensor is manufactured on the basis of a single-chip temperature sensor TCN75A.
