Prylada WASP - Energy Harvesting Wireless Sensor Platform
Designed to collect and transfer data from controlled assets to a host/gateway via Sub-1 GHz channel. The platform can be powered from ambient energy sources and consumes little power.
How the sensor platform works
The platform allows connecting various sensors on board, or sensors can be connected externally through analog inputs or I2C interface. Data collected from the sensors is then transferred to a Prylada gateway or any third-party host/gateway via Sub-1GHz Wi-SUN® network.

Functionality of the two main platform parts
The core’s function is to provide RF communication with a host/gateway and to process information from the sensors. The core is also responsible for energy harvesting from light, heat, vibration, RF, or electromagnetic waves.
The shield is just a carrier for different types of sensors that can be connected to the core.

scenarios
As part of Prylada network
The platform can work within the Prylada networks through LTE or Ethernet Prylada gateways. Once the platform is connected to one of the routers, it gets visible in the Prylada server, cloud-based or on-premises. Using the server, you can configure and update the platform remotely.
As part of third-party network
You can use the platform within third-party networks. In this case, the firmware adjustments are discussed individually.

Competitive advantages of Prylada WASP
The main advantage of the platform is that it lets almost any sensor go truly wireless. In turn, wireless data collection from your critical assets will greatly simplify the monitoring process, reduce the number of cables in your facilities, and ensure real-time alarm management in case of emergency.

Energy harvesting in use*
Energy harvesting means that the platform consumes very little power and can work from different ambient energy sources, such as vibration, solar panels, or heating. The feature is especially important for industrial use. Permanent monitoring of equipment condition at production facilities requires constant operation of sensors and other devices included in the monitoring system. In such circumstances, energy saving practices play an essential role for reducing total production and maintenance costs. Energy harvesting helps the Prylada WASP maximize its battery lifetime and ensure an uninterrupted monitoring process.

How energy harvesting works with different energy sources
In this case, the sensor system gathers solar energy and stores it in a supercapacitor or a Li-ion battery.
As soon as the power management unit (PMU) considers the energy level sufficient, it powers up the microcontroller unit (MCU), which in turn, according to the algorithm, powers up other system’s parts, gathers data from the piggyback module sensors, sets up output signals if necessary, sends processed sensors’ data to the router, and either continues gathering data from sensor or enters deep power down mode waiting for external or internal events to wake up.
The internal backup battery is required to pass cold startup PMU stage when the solar cell provides low voltage.
In this case, the sensor platform gathers thermal energy and stores it in a supercapacitor or a Li-ion battery. The external battery or some alternative power source serves as a backup energy source.
As soon as the PMU considers the energy level sufficient, it powers up the MCU, which in turn, according to the algorithm, powers up other system’s parts, gathers data from the piggyback module sensors, sets up output signals if necessary, sends processed sensors’ data to the router, and either continues gathering data from sensor or enters deep power down mode waiting for external or internal events to wake up. The internal backup battery is required to pass cold startup PMU stage when the solar cell provides low voltage.
In this case, the sensor platform powers from an AC energy source, for instance a vibration transducer.
The energy can be stored in a supercapacitor or a li-ion battery. External sensors are connected in two different ways: I2C interface and through piggyback board converters, if necessary.
External sensors on the I2C bus or the ones connected to the piggybacksensor module can be powered from the 3.3V TWIST power supply. It is uC controllable.
Application
The Prylada WASP can be used to automate control of physical infrastructure at various manufacturing facilities and laboratories. By transferring data from sensors/devices to a remote control center in real-time, you can get a complete picture of the current operations and observe the condition of your equipment.
The use of the sensor platform for condition monitoring and predictive maintenance can help ensure high uptime of your critical assets and avoid unplanned shutdowns of the production lines.
