The integration between the clouds and the sensor networks makes it possible to solve the problem of the limited computing power and the limited capacity of the sensor networks, as well as for the storage and processing of the collected data, without unnecessarily increasing the cost of the sensor networks. A significant challenge is the security of the data transmission connection between the sensors and the cloud. An algorithm has been proposed that ensures security in the transmission of data from the sensor network to the cloud via the DLS security protocol. The algorithm is implemented through the ThingSpeak cloud, and the connection between the sensor network and the cloud is implemented through the MQTT protocol, creating the flow that will gather sensor data, using Node-RED and Generate a self- signed certificate with OpenSSL. The algorithm was tested with Wireshark software, which confirmed that the data packets sent from the sensor network to ThingSpeak use the MQTT data transfer protocol and connect to communication port 8883, which is protected/encrypted via TLS / SSL protocol. 1. Introduction A typical wireless sensor network contains many spatially distributed, self-regulating sensors that jointly monitor and measure various environmental parameters. The sensors provide a variety of useful data that can be used to monitor and control the environment in which they are located. The amount of data generated by sensor networks is enormous, heterogeneous and multidimensional in nature. Significant hardware storage and computing power are required to store and process this data [1]. Unlike traditional networks, WSN has its limitations in design and resources. Resource constraints include limited power, short communication range, low bandwidth, limited processing, and storage in each sensor node . Design limitations depend on the application, which is based on the observed environment [2]. Designing an additional ability to process the collected data leads to an increase in the cost of the sensors. Any increase in the price of a single sensor has a multiplier effect on the total
