Wireless Sensor Network – Newsteo solutions White Paper 1 Introduction Newsteo markets a wide range of products for monitoring various parameters (temperature, humidity, shock ...) for storage and transportation. With Newsteo’s products, it is possible to create wireless sensors networks, for purposes of monitoring or tracking. Several types of architectures are possible to develop the most appropriate solution for the application. The structure of the sensor networks is based on four elements: Element The data logger The radio transceiver The configuration software The display software...

Wireless Sensor Network – Newsteo solutions White Paper Sensor interface Micro processeur Flash Memory Power supply (measurements storage) (battery or main power) Newsteo Data Logger Figure 3 : Block diagram of the Newsteo data logger The data loggers are characterized by several factors: Element The sensor The core Power supply It is placed inside the casing: temperature, humidity, shock ... External It is placed at the end of a probe outside the casing: temperature, humidity, crackmeter, 0-10 V, 4-20 mA ... Used to control the sensor, to wake up and take the measure at the set frequency...

Wireless Sensor Network – Newsteo solutions White Paper 1.2 Radio transmitter - receiver and software The radio transceiver provides a uni or bi-directional communication between the data logger and the configuration software. - Radio communication data logger to transceiver: o Measurement transmission o Alert sending if a threshold is exceeded Radio communication transceiver to data logger: o Sending settings: setting thresholds, resetting the time, frequency measurement, embedded software update ... RF-to-USB Key Ethernet Collector Target Communication protocol Cloud Bi-directional...

Wireless Sensor Network – Newsteo solutions White Paper 2 Create a wireless sensor network The first question to ask yourself is how many collection points (ie radio receivers) and consultation points there will be. For example, if you want to make a temperature measurement in three cold rooms in the kitchen of a restaurant, with one PC to collect and display measurements, you are in a "single-site" installation. Figure 4 : Single-site installation Figure 5 : Multi-site installation The restaurant owner wants to use a PC to collect and display measurements and wishes also to see the...

Wireless Sensor Network – Newsteo solutions White Paper Figure 6 : Multi-site installation It is also possible to equip multiple remote sites and of which the measurements are grouped in a central database, positioned anywhere in the network. In summary: Number of collecting points 1 1 Several Several Number of displaying points 1 (the same than the collecting point) Several 1 Several Installation type Single-site installation Multi-site installation Multi-site installation Multi-site installation

Wireless Sensor Network – Newsteo solutions White Paper 2.1 Create a single-site sensor network 2.1.1 Figure 7 : Single site installation on a PC Required equipment: Element The data logger(s) Radio transceiver Setting software Measurements displaying software The receiving and consultation station Description Any data logger, in the Newsteo catalogue RF-to-USB key for PC RF Monitor Premium version RF Monitor Premium version PC This architecture allows to quickly implementing a real-time monitoring on a site. It is the simplest and the cheapest solution. Note: It is necessary to have...

Wireless Sensor Network – Newsteo solutions White Paper 2.1.2 Figure 8 : Single site installation on PLC Required equipment: Element The data logger(s) The radio receiver Description Any data logger, in the Newsteo catalogue RF-to-Modbus Key for PLC Two versions of receivers are available for connection in RS232 or RS485 to the Programmable Logic Controller The receiving and consultation PLC station This architecture allows you to dialog with the Newsteo data loggers through industrial PLC. It is always possible to use this structure for a multi-site architecture but in this case, the...

Wireless Sensor Network - Newsteo solutions White Paper 2.1.3 Self sufficient via an Ethernet gateway This solution is possible to equip a single site. However, as the collecting station is not the consultation station, it is considered by Newsteo as a multi-site facility (Cf. 2.2 Create a multi-site sensor network). Figure 9 : Single site installation with Ethernet gateway 2.1.4 Comparison of the solutions of single-site architecture Advantage Disadvantage On a PC with RF Easy to install Requires a PC always "on" Monitor Premium Inexpensive solution Non-autonomous solution, "crash" of On...

Wireless Sensor Network – Newsteo solutions White Paper 2.2 Create a multi-site sensor network 2.2.1 With a Collector (Ethernet gateway) The Collector is the easiest and most effective solution to implement a multi-site solution when a network is already present (intranet or internet). Figure 10 : Multi-site installation with Ethernet gateway The Ethernet collector can equip one or more sites. The architecture is as follows: - The data logger(s) send(s) the measurement to the Collector The collector receives measurements and sends them through Ethernet on a database o Generally, the...

Wireless Sensor Network – Newsteo solutions White Paper Required equipment: Element The data logger(s) The radio transceiver Setting software Measurements displaying software The displaying station Description Any data logger, in the Newsteo catalogue Ethernet Collector Webmonitor (web application) Webmonitor or DB Monitor A PC with Internet access Note: Installation is quick and easy by choosing hosting on Newsteo platform (more information on newsteo service at 2.2.4 Database hosted by Newsteo vs. Database hosted by the customer) Several sites communicate to a single database The data...
