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.
The iB005N-SMA is no longer manufactured and has been replaced with the S1-SMA.
The S1 USB doesn’t use batteries and instead uses USB for power. The USB isn’t used to set up the beacon and the manufacturer smartphone app, via Bluetooth, is used instead. The ‘SMA’ means it has an external rather than PCB antenna which moves the antenna away from the device supplying the USB power thus providing better Bluetooth radio signal and longer range. The S1 is also available without an external antenna.
We have a few iB005N-SMA remaining in stock of you particularly need that model.
We have two new thin beacons in stock. The Meeblue U1 and UL1 are only 4.8mm x 45mm x 25.5mm and weigh only 7g.
These beacons are similar to the iB001M in that they are particularly suitable for wearing by humans or animals. These new models have twice the battery power of the iB001M and use the more battery efficient Nordic Semiconductor nRF52 series system on a chip (SoC).
An accelerometer can be used to provide for motion triggered advertising. The accelerometer is only used for motion triggered broadcast and has adjustable movement threshold. They can also be set up to only advertise when the button is pressed. Advertising can be iBeacon, Eddystone UID, Eddystone URI or user defined. In addition, the UL1, has a light sensor that can be set up to cause the beacon to advertise when it’s either dark or light.
