3 in 1 LoRa® Indoor and Outdoor sensor:  Temperature, Humidity and Air Pressure from simple AAA batteries. 

REQUIRES two standard AAA Batteries 

The Sensedge Senstick Microclimate sensor combines several sensors allowing remote monitoring of both harsh indoor and outdoor settings.   Senstick an award-winning LoRaWAN sensor with further functionality and connectivity options to come!

The Things Network Ready | IoT Scotland Compatible

Our sensors are easy to deploy, with a range of mounting options and with standard replaceable batteries, offers wire-free installation.  They are powered by two standard AAA batteries.  The Battery life is estimated to be up to 2 years but depends on sample interval, transmit interval, data rate and environmental factors.   All our Sensedge sensors are equipped with NFC for easy configuration with an Android phone. With this NFC application you can change sample rate, data rate, encryption keys and much more. All of the sensors are built on the LoRaWAN stack from Semtech.

Configuration: All of the Sensedge LoRaWAN Sensors can be self-configured using the Android NFC app “Sensedge“ available from Android Play  . We also offer pre-configuration of sensors and gateways to your choice of The Things Network, private LNS, IoT Platform or other services. Contact us for more information.

Frequency and Certification: All our sensors are CE certified, and available for any region including US902-928, EU863-870, AS923 and AU915-928 . Deceleration of Conformity is only available for the EU and has not yet been certified for compliance with FCC Rules.

Batteries: Professional AAA batteries are recommended given reliable performance across varying temperatures and humidity.

Key features:

・Indoor and outdoor use
・Temperature, relative humidity and air pressure

  • What distance can be achieved with the SenStick

    LoRaWAN is brilliant at long-range and has been seen to travel up to 720KM.  But realistically we suggest that line-of-sight up to 25KM's in rural areas, 3KM's in urban areas and 800metres indoors.  But remember LoRaWAN is based on the law of physics, so obstacles including trees, buildings, walls and even rain can affect signal and therefore distance.  The distance and coverage also based on the Spread Factor manually defined or set by Adaptive Data Rate. We at Concept13 have personally tested this sensor to 5KM's outdoor line of sight, but the rating from the manufacturers is 15KM's.   The image below courtesy of Conwy County Borough Council demonstrating the signal from a comparable sensor, the Elsys EMS.  (The Elsys EMS an indoor sensor - and not recommended for external use as tested here).

  • How long will the batteries last in SenStick sensors

    Senstick have designed brilliant devices capable of using widely available standard alkaline AAA batteries. The firmware and strong adherence to LoRaWAN best practice delivering outstanding reliability and performance over many years.  Battery life is expected to be around 5 years when reporting every 15 minutes, when in a good signal area. But battery life is critically dependant on the frequency of sampling and the Spread Factor determined by the distance (and interference) to the nearest Gateway.  Obstacles such as buildings but also trees and sometimes weather can affect distance resulting in signal loss. When this occurs the Spread Factor will increase (the Data Rate drop) and this will mean more airtime as the message is sent more slowly. This will directly impact the battery life as more power is consumed. We therefore suggest 2 to 5 years as being a good indication and should state the availability and simplicity of changing batteries is an important consideration.

  • How can I decode the SenStick payload

    SensEdge do a brilliant job of compressing the sensor readings to minimise the payload size which means great reliability over larger distances with lower battery consumption.  The SenStick Payload can be decoded using the simple scripts found on their website, or available from Concept13. The following is the Payload Decoder for the Things Network and other LoRaWAN Network Servers Sensedge Senstick SMC20 HWv2.2 */ function Decoder(bytes) { // If Config Packet if (bytes.length == 10) { return { ConfigPacket: true }; } // If Data Packet else { var I1 = bytes[0]; var T1 = (bytes[1] << 8) + bytes[2]; var H1 = (bytes[3] << 8) + bytes[4]; var AP1 = bytes[5]; var MOV = bytes[6]; var BAT = bytes[7]; return { Info: I1, Temperature: sintToDec(T1), Humidity: H1 / 100.0, AirPressure: AP1 + 845, Movement: MOV / 100, BatteryLevel: (BAT + 100) / 100 }; } } function sintToDec(T){ if (T > 32767) { return ((T - 65536) / 100.0); } else { return (T / 100.0); } }

  • How can I configure the SenStick payload

    The SenStick is configured via a very simple NFC app available on Android from the Google Play Store.  Once installed, unscrew the sensor, and find the large black area marked with an NFC logo.  Batteries are not required at this time.  Simply install and launch the app on your Android phone and then tab your Android phone onto the large black area.  It may take time to find the right location on your phone, so please be pattient. Our advice is hold the SenStick the right way up so you can see the "Sensedge" name on the left of the black NFC area, and QR code on the right.  Then very gently tap the phone to the sensor and hold in place for at least five seconds.  If you are unsure of the right spot, repeat and tape the SenStick in a different location on the rear of your phone. Once settings have been read, you can then modify these as required for your private or public LoRaWAN Network Server.
