Build cost-effective ultra-low power wireless temperature and humidity sensors

NeoCortec has released an updated NeoMesh protocol stack version 1.6 firmware for its NC2400 and NC1000 module series to support the new Sensirion SHT4xA temperature and humidity sensor series.

The modules' firmware already includes a generic application layer which can be configured to sample a wide range of sensors so that no programming is needed to implement a wireless sensor device. The release of the new version 1.6 firmware now facilitates easy integration of Sensirion SHT4xA sensors to greatly widen the options to build cost-effective ultra-low power wireless temperature and humidity sensors for use across large areas, e.g. in smart building or agriculture applications.

The company develops a range of tiny modules that enable data collection over large areas and benefit from an average power consumption of as low as 20µA, meaning that modules can run for years on two AA batteries. The modules are all supplied with radio and can be positioned as needed, e.g. around a building or a set of buildings. To start building a NeoMesh network, you only need to switch on two nodes, and the network begins to establish itself. Further nodes added will automatically join the existing network and start expanding it regarding the number of devices and in range. All nodes in a wireless network are equal – each can generate and transmit data. The protocol stack is almost infinitely expandable for most applications, as up to 65K nodes are possible in one network. The technology is pre-certified and well-established. Cost-efficient and straightforward to integrate, the modules suit a wide range of applications based on IoT and Cloud-based sensor networks, including smart buildings and smart workplaces, metering, security, agriculture, transportation, industry 4.0, medical and food distribution.
