Description

AKKR8 Outdoor Sensor A8 STH

The ST-version (S = Solar, T = Temperature, H = Humidity) of AKKR8 is a professional-grade outdoor IoT sensor for temperature and humidity monitoring. Equipped with an external IP65-rated sensorprobe, it delivers highly accurate measurements. The device is equipped with a single probe and can be retrofitted with another 6 temperature probes (Dallas 1-Wire) at a reasonable cost while maintaining accuracy.

Rugged and energy-efficient design

The main unit is protected by a rugged IP65 housing, ensuring dust and water resistance, while the internal electronics operate efficiently to extend battery life and reduce maintenance needs. The front of the device is equipped with a 5W solar panel that charges the device during operation. The device has a built in antenna to ensure integrity.

Each sensor is ready to deploy straight out of the box, providing immediate connectivity via LTE-M cellular networks. Data can be accessed through your preferred IoT platform or via AKKR8’s ready-made packages, which include just the sensor, connectivity, and platform integration.

Sensors, inputs, connections

The AKKR8 Outdoor Sensor A8 STH measures temperature and humidity via an external sensorprobe that is precise and reliable. The sensor comes with a 2-meter cable and is easy to install. It measures temperature once per hour, storing the data in the device and sending it to the platform twice a day, where you can access operational data. The estimated battery life is 100 days, and the measurement frequency can be adjusted as needed. Its rechargeable battery is environmentally friendly, eliminating the need for regular replacements.

All units are equipped with three digital inputs and one output. The first input can immediately wake the device, making it ideal for alarms. The other two inputs are designed for connecting additional sensors. This feature provides flexible integration for monitoring and alert systems.

Easy deployment and flexible connectivity

Each sensor is ready to deploy straight out of the box, providing immediate connectivity via LTE-M cellular networks. Data can be accessed through your preferred IoT platform or via AKKR8’s ready-made packages, which include sensor, connectivity, and platform integration.

Continuous monitoring and actionable insights

The device’s low-power design and long battery life make it ideal for continuous monitoring over extended periods. The external probe can be positioned optimally for accurate readings, while the main unit remains safely housed. The AKKR8 Outdoor Sensor A8 OTH ensures that critical environmental data is always available, enabling timely insights for operational decisions, preventive maintenance, and regulatory compliance.

Reliable solution for demanding environments

With robust construction, precise sensing, and flexible connectivity options, the A8 OTH is a reliable solution for professional outdoor and industrial monitoring applications, providing peace of mind and actionable data in any challenging environment.

Flexible product options

The AKKR8 Outdoor Sensor A8 OTH is offered in three flexible configurations to meet different deployment needs.

Option 1 provides the standalone device, ready to use with your existing IoT platform of choice.

Option 2 allows you to use the sensor with our preconfigured mythings.cloud platform based on ThingsBoard, giving you immediate access to connectivity, data visualization, and analytics.

Option 3 offers a fully custom setup, where we configure your own ThingsBoard instance so you can add additional sensors and fully own the platform, while we handle the initial configuration and deployment for you.

Sensors

High-Precision Sensor Technology

The sensorprobe features a 2 meter cable. The sensor element is a monolithic circuit for measuring humidity and temperature, providing low measurement deviation and hysteresis, along with excellent long-term stability. Humidity and temperature sensors are factory-calibrated, with calibration data stored directly on the chip, ensuring consistent accuracy without the need for recalibration or software adjustments.

Relative humidity sensor: ±3% RH (max), 0–80% RH

High-accuracy temperature sensor: ±0.3 °C (max), -20 to 100 °C

Operating range: 0–100% RH

External Temperature Probes (can be retrofitted)

AKKR8 supports external temperature probes (Dallas 1-wire) that can be connected to the screw terminals on the board with GND, DATA, and 3V3. The 1-wire interface has three screw terminal connections on the board, but it can also be used with devices that have two connections.

When using devices with three connections, the power supply pin should be connected to 3V3; otherwise, it can be ignored. There is already a resistor on the board, so you do not need to connect an additional one.

One-Wire Connection

The AKKR8 sensor is a 1-Wire master and is therefore expected to supply power to the external devices at 3.3 V. You should not supply the AKKR8 with 3.3 V from other devices via the Dallas 1-wire connection.

Multiple Sensor Support

Each 1-Wire slave device has a guaranteed unique address stored in a memory chip. This allows the AKKR8 to manage multiple devices of the same type without conflicts.

You can connect up to six Dallas 1-wire temperature sensors to a single master. Another advantage of Dallas 1-wire is that the signal is not affected by the cable resistance, although a maximum length of 25 meters is normally recommended.

DS18B20 Characteristics

Normal characteristics for a Dallas DS18B20 are that they are intended for a measurement range of -55°C to +125°C, with an accuracy of ±0.5°C in the range of -10°C to +85°C.
