Bluetooth Low Energy
Wireless pulse counter
Efento pulse counter is used to remotely monitor number of events which may be represented by pulses e.g. the number of elements coming off the production line, the number of doors opening/closing or number of people passing through the gate in a store. The sensor can simultaneously work with up to three water meters. Each counted pulse represents one unit, e.g. 1 door opening/closing, one impulse from a gas meter, one change of state of a connected device. Data is presented as the total number of pulse counted in the set time intervals.
You can use a free mobile application to configure the device and read the data from its memory. If you add Efento Gateway, you can build a remote monitoring system
- Pulse counter simultaneously works with up to 3 device with a standard output (SO)
- Measurement period: 1 minute – 10 days (configurable by the user)
- Battery ensures up to 5 years of maintenance-free operation
- Add Efento Gateway and Efento Cloud to build a real time monitoring system. The maximum distance between the sensor and the Gateway is 100 m in the open space and 20 – 30 m in the buildings
- Use a free mobile application to configure the logger, read the data from its memory, generate reports and set alert thresholds
- The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
Key features
Efento Cloud
Together with Efento Cloud, the sensors enable constant monitoring, alerting about exceeding safe limits, generating reports and analyzes.
Long battery life
Loggers have been designed to work for up to 5 years on battery. You can forget about changing the battery frequently or troublesome battery charging.
Lower costs
Choosing wireless sensors and a cloud platform reduces the installation and maintenance costs.
Wide range of sensors
Efento sensors can measure various physical and chemical values. If you decide on one sensor today, you can expand your sensors fleet to another types anytime you want.
Integration
Standard communication protocols allow integration with any cloud platform or mobile application.
Easy set up
All you need to set up a logger is a smartphone with a free mobile application. The whole configuration takes no more than 15 minutes.Universal pulse counter
Efento wireless pulse counter can work with any device equipped with standard output (SO). Moreover, pulse counters can work with different types of sensors (e.g. open close sensor) and count the number of events in the selected measurement period. Efento wireless pulse counter has three channels and can count pulses from up to three devices simultaneously.
Sensor’s passport
Sensor’s passport documents the entire lifecycle of a device. By accessing the data on Efento Cloud platform, the user can check all information about the sensor: date of sale, warranty status, date of calibration, information on all service activities. In addition, the user can download all documents regarding the device – a duplicate of calibration certificate or service protocols.Data security
Data transmitted wirelessly can be encrypted. Thanks to that, unauthorized persons cannot hijack the communication between sensors and other devices. Efento sensors' software can be updated over the air, which will allow you to easily install any security patch that is released.Integration
We believe that the Internet of Things is about integrating data sources, analysing the data and drawing conclusions based on it. If you want to integrate Efento loggers with your software, cloud platform or mobile application, we will provide you with the necessary documentation, libraries, SDKs and we will gladly assist you.
