Nelso Technology Pvt. Ltd. 24 North Parganas, Kolkata, West Bengal

We are manufacturer of DG-Pump, Digital fully Automatic Pump Controller or water level controller for your home and industry. It is suitable for 1 or 3 phase motor. It continuously monitors the liquid level of the overhead tank and reservoir. The Automatic pump controller controls the water pumps and turns it ON and OFF with respect to the level in the water tank. This auto-switching feature saves manpower. Hence no need to operate manually. Our system switches the pump when the level of water in the tank goes below LOW level and OFF when the water exceeds the HIGH level. Thus no wastage of water, stop tank overflow, save water, electricity bill, time and water charges.

The short message system (SMS) of a standard mobile phone can be used for remote site monitoring and controlling various equipments. The SMS service provided by the service providers is comparatively very low cost. The Short Message Service allows text messages to be sent and received to and from mobile telephones. This feature of a standard mobile phone can be implemented for a variety of industrial applications. The main attractive feature of this system is that the user can monitor and control his desired equipments from any part of the world. It works on the basis of Global System for Mobile Communication (GSM). The user may get the status of a remote device like pressure, temperature, voltage, current, On/Off condition, weight etc by sending respectiveSMS to the remote device. The remote device also automatically sends a SMSto the user if any error/alarm occurs during its operation, which is previously defined by the user. The user then may take the necessary action depending on the type of alarm through respective SMS or by any other way

SMS/GSM Remote Water Pump Controller is a device which can control and monitor electric motors, agriculture pump sets through mobile phone. This is aGSM based remote controller to switch ON and OFF pump sets or any electric motor from remote location. This SMS/GSM remote controller helps the farmer to handle agricultural pump sets easily. Farmer can set running time of pump set after it gets ON. It also helps the farmers to save life from snake bite in night time, saves water, time and electricity. One SIM Card is required for its operation.

Nelso Technology have introduced this device for your Child Safety. It’s a Radio Frequency Identification Device (RFID) with cutting age technology. This device also GPRS enabled standalone and completely plug and play device for online student attendance. So it can be placed anywhere and compatible with any SIM card of any network. The device can trace network less than ten seconds and also has capability to change the network mode automatically in worst network area. We provided Smart RFID Student Attendance Systems with SMS for student tracking that track the child's attendance using a simple smart card. RFID tag will be attached to the student ID card and the information related to the student will be attached to the RFID tag. When the student enters the school and swipes the identity card, the reader at the gate will detect the tag and system will recognize the tag according the information stored as per the given record. Then the system will send notification SMS to the parents that their child has entered in the school and the same time the system will store the information for the report purpose. At the time of leaving the school premises, the student will swipes the RFID card once again at the gate and notification via SMS will be sent again to the parents and will also store the data

This product is designed to control two Air Conditioners(A.C. or AC) simultaneously. The industry standard AVR Micro-Controller is the heart of this system. Control over the ACs are performed according to some parameters like temperature, phase voltage, phase current, swapping time etc. User can set or view various parameters like current temperature, phase current, phase voltage, temperature set-point, high room temperature, swapping time, AC trip current, A.C. last trip reason etc. through a 16 x 2 character LCD panel and a status indication panel will help user quickly monitor the status of the ACs. An alarm system generates respective alarm for FMC if any error occurs in the operation. This system keeps the information of last AC trip reason and the overload current at which the Air Conditioner (A.C.) was last tripped in a nonvolatile memory for up to 100 years or the next trip occurs. This devise is fully compatible with VOLTAS SENSICOOL Air Conditioners (ACs) used in the shelter of a mobile tower.
