How to Calibrate Temperature Sensor Beacons?

We have several clients using the temperature/humidity sensor beacons in industrial situations. A question we have had is how is the temperature/humidity calibrated? For scenarios that require monitored temperature/humidity, it’s often necessary to show the readings have been calibrated over time.

M52-SA Sensor beacon

Most sensor beacons don’t have a calibration certificate. The long term drift of the sensor is <0.04C/yr and <0.5 RH/yr so in most applications it doesn’t usually need calibration. If you need accuracy better than this you will usually need to calibrate in the software of the phone/device that receives the beacon signal. That is, you will need to periodically measure the real temperature/humidity using another calibrated instrument and apply any offset to the read values.

S5 Sensor beacon

Another option is to use the one beacon, the S5, that does have a temperature/humidity calibration certificate.

New KKM Wireless Tilt Sensor K9AT

Our partner and supplier, KKM, has a new K9AT Wireless Tilt Sensor The K9AT Tilt Sensor is designed to convert accelerometer measurements into precise tilt angle detections. What makes it stand out is its ability to trigger advertisements once it detects an inclination beyond a pre-set value.

The sensor has an IP67 rating, ensuring it is both water-resistant and dustproof. One of the most impressive aspects of the K9AT Tilt Sensor is its longevity. Powered by an industrial-grade ER14505 battery, it offers an extended battery life of up to 8 years.

The applications of the K9AT are vast and varied. From construction and agriculture to automotive and shipping, this sensor can play a critical role in improving operational efficiency and safety. Its ability to provide real-time alerts on angle changes makes it an invaluable tool for monitoring equipment, cargo, and even structural integrity.

New KKM Waterproof Sensor Beacon

We have the new, waterproof sensor beacon S5 in stock.

This beacon measures temperature, humidity and 3-axis acceleration. It also logs up to 60,000 temperature and humidity records, viewable in the manufacturer’s app. It has a 180m range and also supports Bluetooth 5 coded PHY, when supported by the receiving device, for a longer range of 600m. It’s also the only beacon we know of, that comes with a temperature/humidity calibration certificate.

GATT Connections and Battery Life

Our battery use power testing uncovered some cases where the battery current use during advertising was such that the battery would last longer than manufacturer specification. What was going on?

After contacting the manufacturers, it turned out that some of them include a degree of configuration activity in their battery life estimates. If you only measure the current during advertising then you haven’t taken into account the extra current used during configuration. Configuration via manufacturer apps connects, rather than just listens, to the beacon via Bluetooth GATT. GATT connections consume significantly more power. For one off configuration this will be negligible but if you are in the habit of repeatedly changing the beacon configuration then the battery life will be impacted.

The same goes for platforms/apps that periodically connect to beacons to read, change or monitor beacon parameters. The battery won’t last as long. It’s also for this reason, it’s preferable to read sensor beacon sensor data in advertising data rather than via GATT when this is supported by the beacon and your scenario can cope will less frequently reported data.

New MST01 Industrial Temperature and Humidity Sensors

We have two new industrial temperature and humidity and sensors with built-in displays.

The Minew MST01-02 and MST01-03 are similar except that the latter has the probe on a 1m cable and has a slightly higher maximum 80C temperature rather than 70C for the MST01-02.

Multiple temperature and humidity thresholds can be set. When values are exceeded, there is an audio alarm and a visual indication shown on the screen.

New Bluetooth Water Leak Sensor

We have the new Minew MSL01 water leak sensor in stock.

The two probes are positioned vertically where there’s the possibility of a water leak. Special Bluetooth advertising is sent every second, by default, indicating whether there is a water leak or not, together with the battery level. There’s also an external on-off switch on the back.

The advertising can be picked up by a gateway or detected by scanning for Bluetooth on iOS and Android. The replaceable battery lasts up to 5 years at the default Bluetooth advertising frequency.

New Waterproof Humidity Sensor Beacon

Having a beacon being able to detect humidity (and temperature) while at the same time being waterproof is difficult to achieve because the case itself usually needs to be waterproof thus preventing the sensor on the printed circuit board from sampling the environment. The new M52-PA-S is unique in that it solves this problem by having a permeable seal on the case and a waterproof printed circuit board.


The ‘PA’ signifies this beacon also has an extra RF amplifier for a longer range up to 150m. This beacon can be used in many different modes: 1 channel advertising, 2 channels advertising, 1 + 2 advertising, sensor advertising and Meeblue fixed data. The two main advertising channels can be iBeacon, Eddystone UID, Eddystone URL or user defined. When sensor advertising, the main channels are disabled and advertising includes a unique id, temperature, humidity and battery voltage.

New Human Occupancy Sensor Beacon

The new INGICS iBS08 human detection sensor beacon uses a IT thermal sensor to detect occupancy. It’s better than a PIR sensor beacon in that it can detect the presence of a human even if they are not moving. It’s powered by a CR2450 battery and has a battery life of 1.8 years with a 30-second advertising interval.


There are two models with two distinct angles to cater to a variety of needs. The iBS08S model provides a wide field of view (FOV) of 35 degrees, making it perfect for shorter distance applications, with a detection range of up to 100cm. The iBS08L offers a narrower FOV of 10 degrees, tailored for longer distance applications and boasting a detection range of up to 250cm.

The device are equipped with the latest Bluetooth 5 technology, supporting Coded Phy, with a Bluetooth range of up to 100M.

This beacon is available by special order from BeaconZone.
