Styles of wireless loggers and where they are used!
|Wireless data loggers are becoming more and more popular. This is because they are particularly ideal in applications where near-real-time data is required and manual data offload is impractical. In this article we will cover Bluetooth and Radio Frequency loggers along with WiFi logger, including where they are used and the advantages of each.
Radio Frequency Loggers:Radio Frequency (RF) loggers like the name suggests transmits data by way of an RF signal and use a transmitter (or multiple transmitters depending on the system) and a base station. The transmitter is the logger, these record the information and then transmit the information back to the base station which then receives the information and converts it to useable data.
Where they are used:
• Warehouse monitoring
• Monitoring of vehicles. The sensor can be mounted in the truck and when the truck is inside the warehouse it will transfer data. Upon leaving the warehouse it will continue to store data and will then transfer data automatically as soon as it comes back into range within the warehouse.
• Wine Cellars
• Cool rooms and clean rooms
• Any area where you wish to have all data transferred back to a central location etc.
• Multiple sensors can be installed and all transmit back to the one location
• Generally have a longer battery life than WiFi and Bluetooth loggers
• Ideal for areas where WiFi is not installed
Our most popular RF logger:
Therm-A-lert - Precision wireless temperature data logger
The MadgeTech Therm-A-lert temperature monitoring and alarming system is designed specifically for hospitals, laboratories, pharmaceutical facilities and other critical temperature monitoring areas. The system can be used to monitor a single temperature location or expanded to include hundreds of locations by adding additional transmitters.
This logger also requires the RFC1000 base station:
Wireless transceiver for the RF200 Wireless, RFOT and Therm-A-Lert Data Loggers. Includes MadgeTech Software CD, Software Manual, Quick Start Guide, USB to mini USB adapter and RFC1000 wireless receiver. at all.
Bluetooth loggers transmit by Bluetooth to any compatible device that runs suitable software and that is compatible with the device. These devices collect data and store it in memory, when any paired device such as a phone, tablet or PC are placed within the vicinity of the logger it will transmit the stored data.
Where they are used:
• Wine cellars and cigar cabinets
• HVAC monitoring
• Where constant information is not required and the user is happy to transfer data on an intermittent location when Bluetooth connection can be established.
• Where access is limited and you wish to transfer data in real timed.
• Can be used where access is limited
• Can transfer back to a tablet or phone so a PC is not required
• Generally simpler to setup that an RF or WiFi logger
• No internet access, cables or computer required
Our most popular Bluetooth logger:
MX1101 - HOBO MX Temperature/Relative Humidity Data Logger
Onset’s HOBO MX1101 data logger measures and transmits temperature and relative humidity data wirelessly to mobile devices via Bluetooth Smart technology. The self-contained wireless data logger, which works with Onset’s free HOBOmobile app for logger setup and data management, enables you to access data anytime from your mobile device up to 30m away.
WiFi data loggers use WiFi communication to transmit data. This means that a base station is not required and they can use an existing WiFi connection. The data loggers can be connected to any secured or open WiFi network utilizing a normal WiFi router. These devices will generally have their own memory and data is collected and then transmitted at a predefined interval. The data can either be transmitted back to software running locally on a PC or back to a Cloud depending on the logger and the type of service offered.
Where they are used:
• Hospital Waiting rooms
• Server rooms
• Anywhere were real time data or an alarm is required
• Can be put onto a Cloud based server so that data can be accessed from anywhere
• Has the capability to send email alerts
• Doesn’t require a computer to be on all the time in order to transfer data to it
Our most popular WiFi logger:
WiFi Temperature Probe Data Logging Sensor - EL-WiFi-TP
The EL-WiFi-TP sensor measures the temperature of the environment in which the probe is situated. Data is transmitted wirelessly via a WiFi network to a PC and viewed using a free software package. During configuration the sensor will search for an existing wireless network whilst physically connected to the PC. It can then be placed anywhere within range of the network. If the sensor temporarily loses connectivity with the network, it will log readings until it is able to communicate again with the PC application (max 120 days at 10 second sample interval). The range of the sensor can be increased by using WiFi extenders.The probe can be used in a wide range of temperature situations e.g. manufacturing processes, cold storage and hot storage.
